Atlantica Marmari Beach
Atlantica Marmari Beach is a four-star, all-inclusive family hotel on the quiet northwest coast of Kos, in the Greek Dodecanese, run by Atlantica Hotels & Resorts and sold in the UK as a TUI Blue family hotel. It’s a village of low-rise pastel buildings set among gardens and palm-lined paths, a short walk back from a long, calm, sandy beach that holds a Blue Flag. Families come for that beach, a TUI Kids Club for children from three to eleven and all their meals folded into one price.

Is it worth it?
The quick read before the detail: who Marmari Beach suits, what the all-inclusive gives you and the two things to pin down before you book.
Atlantica Marmari Beach, a four-star all-inclusive on the quiet northwest coast of Kos, is sold in the UK as a TUI Blue family hotel and run day to day by Atlantica Hotels & Resorts. The draw is the setting: a village of low-rise pastel buildings among gardens and palm-lined paths, a few minutes’ walk back from a long, calm, sandy beach that holds a Blue Flag. Families come for that beach, a TUI Kids Club for children from three to eleven run by TUI’s own team and the buffet and à la carte meals folded into one price. It’s a relaxed, spread-out place rather than a lively one, so it suits families who want rest more than a nightly show. Two things are worth pinning down before you book. A crèche for under-threes ran here last season but can’t be confirmed for now, so don’t count on one for a baby without checking with TUI first. The all-inclusive also gives you one dinner per stay at each à la carte restaurant, but one of the three is adults-only, which leaves a family two of those dinners rather than three.
Best for
You want a calm, sandy Blue Flag beach, a TUI-run kids’ club for threes to elevens and all your meals and drinks in the price, in a quiet, spread-out garden setting.
Maybe not for
You want lively entertainment every night, a big waterpark of slides, or a crèche for a baby you can count on.
Best ages
Threes to elevens are the best served, by the TUI Kids Club. Babies and toddlers are well fed but have no confirmed crèche this season.
What stands out
The long sandy beach with its gentle shelf, the village-style gardens and the relaxed, quiet feel.
What to check
Whether the BabyClub for under-threes is running for your dates, and the airport coach transfer time.
Where is it?
On the northwest coast of Kos in the Greek Dodecanese, at Marmari, about 15 minutes by taxi from Kos airport.
Quick facts for families
What the resort is like
How the hotel is laid out, what it means for getting around with a pushchair and the services on site.
Atlantica Marmari Beach is built as a village rather than a single block. Low-rise, pastel-coloured buildings sit among lawns, palm-lined paths and pools, so it feels park-like and spread out, and you walk between your room, the pools, the restaurants and the beach. It’s a medium-to-large resort. Right next door is a separate, higher-category Atlantica hotel, the Marmari Palace, which is easy to confuse with this one when you’re searching or booking, so check you’re looking at Marmari Beach.
The garden paths are mostly flat, so getting around the grounds is manageable with a pushchair, though the spread means some walking between the far blocks, the pools and the beach. If you’d rather not carry a pushchair upstairs, ask for a ground-floor or low room when you book.
Reception is staffed around the clock, there’s free parking and free Wi-Fi throughout the public areas, plus a porter service, a free luggage room and public transport nearby. A number of extras carry a charge: a kiosk and mini market on site, laundry and dry-cleaning, lockers in the luggage room, a taxi service, car rental arranged nearby and a doctor on call day and night. For the wider island beyond the gate, its beaches and when to go, see our Kos guide.
Every restaurant and bar
The main buffet, the three à la carte restaurants, the snack outlets and bars, then how the à la carte booking works.
The all-inclusive covers the buffet meals, the all-day snack outlets and one dinner per stay at each of the three à la carte restaurants. The included food and drink stops at midnight. There are four restaurants, two all-day snack outlets and two bars, plus a coffee-and-juice bar that sits outside the package.
The Main Restaurant is the buffet, open for breakfast, lunch and dinner, with Greek, Mediterranean and international dishes and themed buffet evenings through the week. It’s casual and needs no reservation, so you walk in whenever a child’s appetite arrives. For families it’s the most useful room: there’s a dedicated kids-and-babies buffet section, an early breakfast service for feeding little ones before a beach day and packed lunch baskets you can take out for a day away from the hotel.
Ammos is the Greek à la carte restaurant, open for dinner only, smart casual, with sea views. A reservation is needed, and it’s open to families, so it’s one of the two à la carte dinners a family can use.
Elia is the Mediterranean à la carte restaurant, dinner only and smart casual, with garden views. It’s adults-only, so families with children can’t dine here.
The Fork House is the American diner and steakhouse, dinner only, with flame-grilled steaks, burgers and salads in a relaxed, diner-style setting that tends to appeal to children. A reservation is needed, and it’s the second à la carte restaurant open to families, alongside Ammos.
For lighter meals through the day, Snacks by The Fork House and Snacks by Ammos serve hot and cold snacks, the latter poolside, both included in the all-inclusive. The J&C Spot is a coffee bar with fresh-pressed juices, and it’s the one food outlet that isn’t part of the package, so drinks there are charged extra, which catches some guests out.
For drinks, there are pool bars serving beer, wine, spirits and soft drinks, one of them a swim-up bar. In the evening the Lounge Bar does cocktails, alcohol-free drinks and hot drinks, with indoor and outdoor seating. There’s a beach bar for a drink by the shore too, which is one of the poolside bars near the sand rather than a separate outlet. All of these are included, though premium wines and spirits outside the all-inclusive selection are usually extra.
How the à la carte booking works
All three à la carte restaurants take reservations, with one dinner per stay at each included in the all-inclusive. The booking is handled at the hotel, so the simplest approach is to ask at reception when you check in, sort your dinners early in the stay and take the earliest sittings if you have young children, since those tend to go first. With Elia adults-only, a family’s two à la carte dinners are at Ammos and The Fork House.
Rooms and suites
The room types and which suit a family, then the pools and the sandy beach a short walk away.
The hotel offers standard double rooms and larger two-bedroom family suites, with a choice of sea, pool or garden outlook. The table below gives the fit for each; where an exact size or occupancy limit matters for your family, confirm it with the hotel or TUI when you book.
| Room | Sleeps | Views | Family fit |
|---|---|---|---|
| Double Room | 2 | Sea, pool or garden | The standard room, for two adults, with no separate bedroom to close off |
| Two-Bedroom Family Suite | Up to 5 | Sea, pool or garden | Two bedrooms and a balcony or terrace, the choice for a family who wants a door to shut on a sleeping baby or toddler |
Every room comes with air conditioning, Wi-Fi, a satellite television, tea and coffee-making facilities and a safe, along with a private bathroom, a balcony or terrace, a work desk and toiletries. The double rooms sleep two and aren’t family rooms, so they suit two adults rather than a family who needs a separate sleeping space. The two-bedroom family suites sleep up to five and give you a second bedroom with a door to shut, which is the layout to book for a baby or toddler who needs to nap and sleep while parents stay up.
Pools and water features
There are three main pools: two outdoor pools and a third with waterslides, along with a swim-up pool bar. Guest accounts also describe two smaller children’s pools, partly shaded, and a shallow baby pool for the youngest, though the hotel’s own pool listing doesn’t break these out. There’s no separate adults-only pool and no heated pool. Sunbeds line the pools, and whether the loungers and pool towels are included or cost extra is worth checking when you book.
The beach
Marmari beach is the resort’s strongest asset, a long stretch of golden sand, well over two kilometres of it along the wider bay. It holds a 2026 Blue Flag, an award that requires excellent water quality among other standards. Protected by the Turkish coast opposite and a shallow shelf, the water is calm and shelves in gently, so it stays shallow a long way out, which is what you want with toddlers.
It’s a short walk of a few minutes, roughly 300 metres, from the main grounds to the sand, with some rooms opening more or less straight onto it. Sunbeds line the shore, and whether beach loungers are included or cost extra is worth checking when you book. Water sports are run on the beach by an outside provider, so they sit outside the all-inclusive.
Babies and toddlers
What the hotel does well for the youngest guests, and the crèche question to settle before you book.
The hotel does well at feeding a baby or toddler. The Main Restaurant has a dedicated kids-and-babies buffet section, which helps with weaning and with picky eaters, along with an early breakfast service and packed lunch baskets for days out. Cots and high chairs are standard at all-inclusive family hotels, so request them when you book. The doctor on call day and night, though charged for, is a reassurance with a baby.
One thing to pin down is the crèche. A BabyClub for under-threes ran here last season but can’t be confirmed for the current one, so if it’s central to your booking, check directly with TUI that it’s running for your dates. Don’t build your plans on it.
Things to do
The TUI Kids Club is the main provision for children, run by TUI’s own team rather than hotel staff, six days a week with one day off. It splits into Minis for threes to fives and Maxis for sixes to elevens, with arts and crafts, sports, games, themed activities and a mini disco. It’s usually part of the all-inclusive, though worth confirming when you book. There’s no dedicated teen programme.
Beyond the club, there’s a playground and painting for children, both included, plus a game centre that’s charged extra. For sports there are tennis and padel courts, a gym and mini golf; check which of these are included when you book. A daytime animation programme runs through the day, and the evenings bring shows and a mini disco, though the evening programme is on the quiet side (more on that below). Water sports on the beach and horse riding are run by outside providers and cost extra.
The spa offers treatments, tailored therapies and a manicure and pedicure. The treatment menu and prices aren’t published, and spa treatments sit outside the all-inclusive, so budget for them separately.
The area and days out
Marmari village has a small centre with tavernas and shops within walking distance of the hotel, roughly 10 to 15 minutes on foot. A short drive away is the fishing village of Mastichari, with fish tavernas around its harbour and a ferry point for the island of Kalymnos. Kos Town is about 9 miles (15 km) east, with its harbour, the medieval Neratzia Castle and the ancient Asklepion healing sanctuary; there’s no walkable link, so you’ll want a taxi or a hire car, and the KTEL bus service also runs the Marmari to Kos Town route, though timetables are worth checking locally.
For more beaches, Tigaki lies east of the hotel with more golden sand, Mastichari beach to the west has a water-sports feel and Kefalos to the south pairs a sandy beach with ancient ruins. Marmari village has at least one pharmacy for the everyday bits, the main hospital is in Kos Town and Greece uses the euro with cards widely accepted. The FCDO’s advice for Greece is standard, with no elevated risk as of its April 2026 update; check gov.uk before you travel.
Loves and gripes
What guests rate and what they flag, how it sits against the other Kos family hotels, the journey and the weather.
The picture across the review sites is positive. Atlantica Marmari Beach is consistently well reviewed on TripAdvisor, Google and the German TUI site, sitting among the better-rated family hotels on Kos.
What families love
- The sandy, calm, gently shelving beach, the feature families rate most.
- Friendly, attentive staff.
- Clean rooms and well-kept grounds.
- The food, for its quality and the variety of the themed buffet evenings.
- The TUI Kids Club for children from three to eleven.
- The relaxed, quiet, peaceful atmosphere.
- The village-style layout and gardens.
Worth weighing
- The evening entertainment is quiet and limited, a letdown if you want a nightly show.
- Elia being adults-only leaves a family two à la carte dinners rather than three.
- The J&C Spot coffee and juice bar isn’t in the all-inclusive.
- The multi-stop coach transfer can feel long against the 15-minute taxi.
- A few accounts mention some rooms feeling dated, though the hotel is well kept overall.
- A few accounts mention the pools feeling busy at the July and August peak.
How it compares
Within the Kos family shortlist, Marmari Beach is the calmer, sandier, TUI-run option rather than the biggest or the splashiest. Akti Beach Club at Kardamena has more pools and a club that reaches younger children, but it sits on a livelier strip; Marmari is quieter with a sandier beach. Blue Lagoon Resort at Lambi has a bigger splash and waterslide complex and sits closer to Kos Town, so it suits families who want more water play, where Marmari is the calmer option with the sandier beach. White Olive Marine Aquapark at Tigaki builds in an aquapark with a wave pool for children of four and up. At the top end, the five-star Mitsis Blue Domes at Kardamena is a much larger ultra all-inclusive with nine pools and seven restaurants, and Grecotel LUXME Kos at Psalidi is a calmer, design-led five-star; both cost more, with Marmari Beach the more accessible price point. Its case rests on the calm sandy beach, the managed TUI programme for threes to elevens and the quiet, relaxed feel, not on the longest restaurant list or the biggest waterpark.
The journey and bookingGetting there and when to go
Kos International Airport is about 7 miles (12 km) from the hotel, served by TUI, Jet2 and easyJet among others from UK regional airports. A direct taxi covers it in about 15 minutes; the TUI coach transfer takes 45 minutes to an hour, because it calls at several hotels, so confirm the time with TUI when you book. The transfer has to be booked in advance rather than laid on automatically, so arrange it when you book. The hotel is sold in the UK through TUI and also through Jet2holidays, so it isn’t a TUI-only property.
The hotel opens from late spring to early autumn. For families with young children, June is quieter with the heat still building, July and August are the hottest and busiest weeks with midday heat to manage, and September is warm, quieter and good value.
Weather
Kos has a hot, dry Mediterranean summer, with high summer all but rainless and the sea warmest in August. The table below covers the hotel’s season. One local note: the northwest coast catches the Meltemi, a summer wind that eases the July and August heat but can make the sea a little choppier for swimming on a breezy afternoon.
| Month | Daytime high | Overnight low | Rain | Wet days | Sea temp |
|---|---|---|---|---|---|
| January | 14° | 9° | 170 mm | 12 | 18° |
| February | 15° | 10° | 115 mm | 10 | 17° |
| March | 16.5° | 11° | 75 mm | 9 | 17° |
| April | 20° | 13.5° | 35 mm | 7 | 17° |
| May | 24° | 17° | 20 mm | 5 | 20° |
| June | 28° | 21° | 8 mm | 3 | 23° |
| July | 31° | 23° | 2 mm | 3 | 24° |
| August | 31° | 23.5° | 5 mm | 3 | 26° |
| September | 28.5° | 21.5° | 15 mm | 3 | 25° |
| October | 24° | 18° | 60 mm | 6 | 23° |
| November | 20° | 14.5° | 90 mm | 8 | 22° |
| December | 16° | 11° | 135 mm | 12 | 20° |
Typical monthly averages from weather-station records. Sea temperature is the open-water figure, so a sheltered bay can feel a degree or two warmer. The hotel opens roughly from late spring to early autumn; Marmari’s beach flies its Blue Flag from 1 July to 31 October.
Questions
The things families ask most, the official pages worth a look and when this guide was last updated.
How many à la carte dinners do we get, and what about the other nights?
The all-inclusive includes one dinner per stay at each à la carte restaurant, and with Elia adults-only that means two à la carte nights for a family. Every other dinner is the buffet, which needs no booking and is the easier option with young children anyway, since you can walk in and leave when a toddler has had enough.
Is there a crèche for a baby?
There was a BabyClub for under-threes last season, but nothing’s confirmed for now, so check with TUI for your exact dates before you book. If it isn’t running, the TUI Kids Club only starts at three, so with a baby you’d be looking after childcare yourselves. Don’t book on the strength of the crèche alone.
Can we get a pushchair to the beach?
It’s a short walk of a few minutes from the grounds to the sand, on mostly flat garden paths. Soft sand is hard going with a pushchair though, so a sling or carrier is worth packing for the last stretch and for the beach itself.
Is the airport transfer worth booking as a taxi instead?
A taxi covers the 7 miles (12 km) in about 15 minutes, while the TUI coach takes 45 minutes to an hour because it stops at several hotels. The coach has to be booked in advance rather than laid on automatically, so arrange it when you book; if a short first day with a tired toddler matters most, a private taxi is the quicker option.
What do we need for entry to Greece?
A UK passport, with at least six months’ validity recommended. Under the April 2026 FCDO advice, UK travellers are currently exempt from the EES biometric checks Greece is bringing in, but that can change, so check gov.uk before you travel.
