Karaada Bodrum Guide: Thermal Cave, Bays and Boat Route 2026

Why Karaada, and Why Now? Bodrum's Quieter Island

Karaada — literally "Black Island" — sits at the mouth of Bodrum harbour, close enough to see from the marina but far enough to feel removed from it. Through July and August hundreds of boats anchor around it in shifts. From October onwards the island turns into something else entirely: the sea is still warm, the sky is usually clear and the bays are almost empty.

Long-term averages put Bodrum's sea temperature at around 23°C in October and roughly 20°C in November, which means the "season is over" line does not really apply until late October. If you want a month-by-month breakdown, see our when to visit Bodrum guide.

Daily boat trips usually run from April to November, departing at 11:00 and returning between 16:30 and 17:30. That leaves a full autumn window for Karaada, and with fewer boats around you can stay longer in each bay instead of queuing for a spot in the water.

Karaada Practical Information: Access, Times, Season and Prices

There is no road to Karaada; the only way in is by sea. Here is what you need to know before you plan.

• Location: At the entrance of Bodrum harbour, roughly 4 nautical miles (6-7 km) from the town centre. It is the largest island off the Bodrum peninsula.
• Access: Daily boat tours, private boat or gulet charter, or your own vessel. There is no scheduled passenger line.
• Departure point: Halikarnas Harbour in central Bodrum (Kumbahçe).
• Season: Group tours generally run daily between April and November; in winter, regular daily departures are hard to find.
• Times: A typical programme runs 11:00 to 16:30-17:30, about 5-7 hours in total.
• Advertised 2026 prices: Around 1,200-1,300 TL per adult, roughly 600-750 TL for children aged 7-12, and usually free for ages 0-6. Prices vary by operator and boat type.
• Included: Lunch (typically grilled chicken, pasta and salad) and the swimming stops throughout the day.
• Not included: Drinks (usually bought from the boat bar), personal expenses and the entrance fee for the thermal cave.
• Accommodation: There is no village, housing or hotel on the island. Staying overnight requires a gulet or boat.

Because prices move with the season and the operator, confirm the exact figure the day before you sail. To compare other routes and concepts in Bodrum, read our Bodrum boat tour guide.

The History of Karaada: From Arkonnesos to Today

Known in antiquity as Arkonnesos, the island has always been a shelter and lookout point thanks to its position at the mouth of the gulf. During Alexander the Great's siege of Halicarnassus in 334 BC, part of the Persian garrison withdrew to the island after setting the city on fire. For the ruins of the ancient city itself, see our Mausoleum at Halicarnassus guide and the Myndos Gate article.

In the Middle Ages the Greeks called it Arkos, and it passed to the Knights of St. John together with Bodrum. The Ottomans took the island in the 16th century, and in 1919 it was occupied by Italy along with Bodrum, before being returned to Turkey under the 1932 Italy-Turkey Convention.

Today Karaada is the biggest island on the peninsula but has no settlement, housing or hotel. Pine forest, rocky shores and a handful of abandoned structures make it one of the most unspoiled corners of the region - the reason many visitors searching for "Bodrum Island" end up discovering a day-trip destination instead.

The Thermal Cave: What Makes Karaada Special

The island's signature stop is its thermal cave. Mineral-rich water emerges from a cave at sea level and mixes with the Aegean between the rocks. Sources put the temperature at around 32°C, noticeably warmer than the surrounding sea, and describe the water as rich in magnesium, sulphur and calcium.

The sulphur smell is unmistakable and can be surprising at first, but spreading the cave clay over your skin and rinsing it off in the sea has become a small Bodrum ritual. Legend says Cleopatra used the same mud for her skin; this is a legend rather than a documented fact, so it is best treated as a story told around the bay.

The area around the cave is rocky and sometimes slippery. Water shoes, a towel, a spare swimsuit and a waterproof phone pouch make the stop far more comfortable. There is a small entrance fee at the facility, not included in the tour price, so carry some cash.

The Boat Route: From the Cave to Rabbit Point

The classic Karaada tour leaves Halikarnas Harbour and makes four or five swimming stops during the day. The exact order and number depend on the operator, sea traffic and weather, and captains reserve the right to change the route. The headings below cover the most common stops.

Meteor Bay

Meteor Bay lies within Karaada and cannot be reached by land - only by boat. Named after its crater-like shape, it is one of the calmest bays in Bodrum, and because access is difficult it stays relatively quiet. In autumn, anchoring here can be the most peaceful hour of the day.

Poyraz and Aquarium Bay

These bays on the island's north-eastern side are known for water so clear it looks like an aquarium, which makes them the first choice for snorkelling. Boats switch between the bays depending on wind direction; on breezy days the captain picks the more sheltered option.

Kızılburun and the Dalgıç Bay Area

Kızılburun ("Red Point") takes its name from the reddish-brown rock and usually offers a short swimming stop. Dalgıç Bay and the Alarga area are prized for their underwater life and are also used by dive boats. Above the surface the cliffs look ordinary; below them lies one of Bodrum's most popular dive zones.

Rabbit Point (Tavşan Burnu)

The final stop is usually Rabbit Point, said to be named after the local hare population. With a sandy strip and shallow water, it is the easiest place to swim with children. For other sandy beaches on the peninsula, see our guide to the best beaches in Bodrum.

Diving Around Karaada: Wrecks and Reefs

Karaada is the first name that comes up when divers talk about Bodrum. Dozens of dive sites ring the island, including Paçoz, Kaçakçı, Poyraz, Meteor and Alarga Bay, many of them suitable for beginners. Because it is a short ride from the centre, most daily dive trips include the area.

One of the best-known wrecks here is the TCG Y111 Pınar 1, scuttled at Karaada's Poyraz harbour in 2007 to create an artificial reef. The roughly 37-metre vessel now sits on the seabed as a dive attraction. Water temperatures vary by season, and the local dive season generally runs from April until October or November.

If you want to try a discovery dive, licensed dive schools in Bodrum offer equipment and training; our Bodrum diving guide lists the details. For the region's underwater history, the Museum of Underwater Archaeology article is a useful companion.

Karaada in Autumn: Weather, Sea and Crowds

Autumn is not only about fewer people; conditions tend to be more balanced too. The short list below sums up the shift.

• October: Sea temperature averages around 23°C, daytime highs sit in the low twenties and rainy days are still rare.
• November: The sea drops to roughly 20°C - short swims remain possible, longer ones feel cold. The sky is more changeable and the wind more noticeable.
• Tours: Group day trips run between April and November; in winter departures thin out and access mostly depends on private charters.
• Crowds: In summer several boats anchor in the same bay; in autumn you will often have it to yourself.
• Season length: Industry representatives report that the season in Bodrum now stretches into November and that hotel occupancy stays high in October, which means autumn is no longer a dead season for either accommodation or boat trips.

That said, autumn weather in Bodrum can change from one day to the next. A sunny morning often turns windier in the afternoon, so flexible dates and a clear cancellation policy help. If you are driving and it is your first visit, our getting to Bodrum guide explains distances across the peninsula.

How much does a Karaada boat tour cost in 2026?

Listings for the 2026 season show around 1,200-1,300 TL per adult and roughly 600-750 TL for children aged 7-12, with ages 0-6 usually free. Lunch is included and drinks are not. Prices vary by operator and season, so confirm before booking.

Yes, a small fee is charged at the facility and it is not included in the tour price. Bringing cash is practical, and water shoes are recommended because the area is rocky.

Is there any accommodation on Karaada?

No. The island has no village, housing or hotel and works as a day trip. To spend the night at sea you would need to charter a gulet or boat.

Can you swim in Bodrum in autumn?

In October the sea averages around 23°C, which is comfortable. In November it falls to roughly 20°C - fine for short swims, chilly for long ones. On windy days it is best to let the captain choose the most sheltered bay.

Can you dive around Karaada?

Yes. Sites such as Paçoz, Kaçakçı, Poyraz, Meteor and Alarga Bay suit different experience levels, and there are wreck dives in the area. Without experience you should join a licensed school for a discovery dive.

Yes. Shallow, sandy stops such as Rabbit Point work well for families, and children aged 0-6 usually travel free. Life jackets while the boat is moving and sun protection are essential.

Conclusion: How to Plan Your Karaada Day

Karaada remains the classic Bodrum boat route, but treating it as a single swimming stop misses the point. Between its ancient history, its mineral thermal cave, its dive sites and its very different bays, one day is enough to see it - and usually not enough to be done with it.

October and November are the sweet spot: warm water, working tours and quiet anchorages. Start with the classic 11:00 departure to get your bearings, and next time ask the captain to anchor straight in Meteor Bay or off Poyraz.
