An Alanya boat cruise usually means a half day on the water: you sail beneath Alanya Castle, look into sea caves and stop in a cove for a swim. Most trips leave from the harbour below the castle rock.
TurB2C lists several boat trips from Alanya, from a 4.5-hour catamaran or pirate boat to a 7.5-hour Green Canyon day. All of them list hotel pickup and free cancellation, and most include lunch on board. Below you will find the route, how the trips differ and what to pack.
The classic route runs along the coast under Alanya Castle, past the old shipyard and into the sea caves. The catamaran cruise names the ancient shipyard of Coracesium and the caves and coves along the shore. The relaxing cruise lists the castle, the sea caves, swim stops in secluded coves and lunch on deck. Expect to spend a lot of the day on deck, with swimming whenever the boat anchors, so the time in the water is part of the plan.
The catamaran cruise (4.5 hours, lunch and soft drinks) suits a calm, sightseeing-focused outing with some history about the coast and its pirates. The pirate boat (4.5 hours) is livelier: it lists snorkelling, several decks, live entertainment, lunch on board, unlimited soft drinks and a crew with a guide. The relaxing cruise (5 hours) is the slowest paced. The night jeep safari package adds a boat trip of about 2 hours to the Phosphorus Cave and a swim stop at Cleopatra Beach.
Not a river cruise in the usual sense. The nearest option is the Green Canyon boat tour (7.5 hours), which takes you on a scenic cruise on inland water instead of the sea. The day also includes a cabrio safari with a foam party, water fights at designated spots, a photo stop at the Manavgat Dam and lunch at a local restaurant with a swim. If you want a river without a boat, the Sapadere Canyon tour (6 hours) ends with lunch beside the Dim River.
The sea is warm enough for swimming from roughly May to October, so that is the most comfortable window. Bring a swimsuit, a towel, sun cream, a hat and sunglasses, and snorkelling is easier if you have your own mask. None of the listed cruises is a sunset sailing, so check each tour page for its schedule before booking. All boat trips list hotel pickup, and the relaxing cruise offers a round-trip transfer as an option, so confirm it when you choose.
