Things to do in Alanya for free mostly means walking: the old harbour, the Red Tower and the public beaches are all open to explore without booking a tour. Start early, since the castle hill and old town are easier to cover before the midday heat.
The four tours listed on TurB2C are paid excursions rather than free ones, so this guide keeps them in their own section. If you want a day on the water, a canyon walk or an off-road drive with lunch and hotel pickup, they make a good addition once you have seen the town.
The old town sits below Alanya Castle on its peninsula, and the climb up the walls is the classic walk, with wide views over the bay. Down by the harbour, the Red Tower (Kızıl Kule) is a 13th-century octagonal tower you can circle on foot. The nearby shipyard, the Tersane, dates from the same Seljuk period as the castle and marks the ancient shipyard area of Coracesium. Walking the harbour promenade in the late afternoon gives you boats coming and going and the peninsula lit up over the water. Wear closed shoes for the stone paths, carry water and allow a couple of hours to take it slowly.
Cleopatra Beach is a well-known public stretch of sand close to the old town, and you can reach it on foot and use it without a reservation. Public beaches in Alanya are open for swimming, so you can bring your own towel and spend the afternoon in the sea. Summer days can be busy, so arriving before mid-morning or in the late afternoon makes things more comfortable. Follow any posted signs about sea conditions, and remember that the sun is strong on the Mediterranean coast even when the water looks calm.
None of the four tours on TurB2C are free, but each covers ground the free walks do not. The catamaran cruise (4.5 h) includes lunch, soft drinks, visits to hidden caves and mysterious coves, and a look at the ancient shipyard of Coracesium. The pirate boat (4.5 h) adds round-trip hotel transfers, lunch, unlimited soft drinks, live entertainment and a chance to swim and snorkel. The Sapadere Canyon tour (6 h) takes you to the Cüceler (Dwarves) Cave and along wooden walkways past waterfalls and natural pools, with lunch at a riverside restaurant on the Dim River. The Jeep Water Fights Safari (6 h) crosses the Taurus Mountains with hotel transfers both ways, a guide, full insurance and lunch.
Pick one or two free walks and one paid tour so the day does not run too long. The castle and harbour are easier in the morning, while beach time and boat trips suit the middle of the day. Bring sun cream, a hat and water. If you book a tour, check the start time and pickup details with your hotel, since all four tours on TurB2C list hotel pickup and free cancellation. Leave some time for a slow lunch in the old town between sights.
