Kaş Swimming Tours Guide: Best Bays & Sea Temperature

Picture the moment you first slip into the water in Kaş: you can see the pebbles beneath your feet from metres above, and the sea is so clear that, looking down from the boat, it feels like floating in mid-air. But there is a small catch. Kaş's coastline is mostly rocky, and most of its most beautiful bays are either very hard or impossible to reach by land. The town beaches also get crowded in summer. That is exactly why Kaş swimming tours are the most practical way to discover the region's true beauty. If you want to swim in several different bays in a single day, a small-group Kaş island hopping tour gives you a day fully focused on swimming, far from the crowds.

In this guide, you'll find where to swim in Kaş, how warm the sea is month by month, and what to keep in mind before you head out on a tour.

Why Is Kaş One of the Most Special Places to Swim in the Mediterranean?

What sets Kaş apart from other holiday destinations is the extraordinary clarity of its sea. Because the coastline is rocky rather than sandy, the water rarely turns cloudy. For snorkellers, that means excellent visibility; for open water swimmers, it means a calm, transparent sea where it's easy to find your bearings.

The region's geography is another advantage. The waters off Kaş are dotted with islands large and small, and the coastline is full of coves and inlets. Since these islands break the wind and waves, many bays stay sheltered even when the afternoon breeze picks up. The view of the Greek island of Meis (Kastellorizo) just across the water adds a special touch to the scenery.

The Best Swimming Bays Around Kaş, Reachable by Boat

Kaş swimming tours usually stop at several different spots depending on the day's weather and wind. Here are some of the most popular swimming spots.

Liman Ağzı

Lying directly across from Kaş harbour, Liman Ağzı is one of the closest bays to town, yet one of the hardest to reach by land. With its calm, sheltered water and a shoreline framed by Lycian rock-cut tombs, it's ideal for both swimming and relaxing. The water is usually still, so even beginner swimmers feel comfortable here.

Pigeon Island and the Kaş Peninsula Coast

The steep cliffs along the Kaş Peninsula make a wonderful route for open water swimmers. The area around Pigeon Island is especially enchanting close to sunset. The colourful fish around the base of the rocks are plentiful enough to surprise anyone looking through a snorkel mask.

Kekova and Aquarium Bay

Kekova is famous for its sunken city ruins, but it is also one of the region's gems for swimming. Once you jump into Aquarium Bay, named for the clarity of its water, you'll immediately understand where the name comes from. Because the Kekova area is protected, swimming over the submerged ruins is forbidden, but you can swim as much as you like in the surrounding bays.

Aperlai: Swimming in the Shadow of Ancient Ruins

Part of the ruins of the ancient Lycian city of Aperlai now lies under water. Seeing ancient walls along the shore while swimming in its calm bay is one of the most unforgettable experiences Kaş has to offer. It's hard to find another swimming spot where history and nature are so intertwined.

💡 Captain Ergun's Tip: Kaş's shoreline is rocky, so always bring water shoes; they're the easiest way to protect yourself from sea urchins. If you bring your own snorkel mask, you'll know it fits your face properly. And remember: the water is at its clearest in the morning, so don't miss the first swim stop.

Swimming in Kaş All Year Round: Sea Temperature by Month

In Kaş, the sea is open for swimming 12 months a year, and boat tours run all year round. According to long-term measurements, even in February and March, when the water is at its coldest, the average sea temperature is around 17°C; in December it's around 20°C, and in January around 18°C. The sea starts warming up in spring, reaching an average of 20.5°C in May and 24°C in June, before hitting its warmest period in July and August with averages of 27–29°C.

Autumn is many swimmers' favourite season. The water averages 28°C in September, 25°C in October and still around 22.5°C in November, and with the summer crowds gone, the bays are much quieter. In winter, you can have the bays almost entirely to yourself. Whatever the season, joining a Kaş island hopping tour lets you enjoy Kaş's crystal-clear waters in its most beautiful bays.

Preparing for Your Swimming Tour: What Should You Bring?

When heading out on a full-day swimming tour by boat, it's important to pack light but completely. Sunscreen, a hat and sunglasses are your first line of defence against the Mediterranean sun. We recommend bringing a towel, a spare swimsuit and a light layer for windy moments. Water shoes and a snorkel mask are must-haves for a swimming tour. A waterproof case for your phone or camera protects your belongings and lets you take photos underwater.

💡 Captain Ergun's Tip: If possible, choose reef-safe sunscreen that doesn't harm marine life, and apply it at least half an hour before getting in the water. In Kaş, a breeze picks up in the afternoon, so we decide which bays to swim in each morning based on the wind. If your captain changes the route, it's to take you to calm, sheltered water.

Frequently Asked Questions
