Things to do in September
- In dry weather, the castle peninsula offers historic walls and views of the city and sea. Its elevated setting makes this a more active walk than a stroll beside the harbour.
- The harbour offers a view of the Red Tower, an octagonal structure from the Seljuk period. It is an option for time by the water without climbing the whole castle peninsula.
- For a rainy day, Alanya Archaeological Museum offers indoor displays about seafaring, the castle and local history, including a bronze Heracles.
