A rental car turns Kalkan into a base for the richest day trips on the Lycian coast. Patara is the best first outing, pairing a major archaeological site with a long beach stop on a single 15 euro ticket. The UNESCO ruins of Xanthos sit nearby at about 3 euro entry, and Kas is an easy 29 km along the D400 for harbour dining and Kekova boat trips. Saklikent Gorge adds a dramatic canyon walk inland. If your week includes several paid sites, the MuseumPass Akdeniz at 90 euro for 7 days can pay off. A sensible plan is three days minimum — Patara plus Xanthos or Letoon on day one, Saklikent and Islamlar on day two, and Kas with Kekova or Myra/Demre on day three — with an extra day for Fethiye and Oludeniz.
