A wide range of boat trips operate from Belceğiz, to some beautiful and fascinating destinations including remote coves, islets such as Gemiler, and Byzantine ruins. Among the potential pitfalls are limp lunches, bored guides and stops that are either rushed or missed out altogether.
The cheapest and most popular destination is the so-called Butterfly Valley (Kelebek Vadisi), a beach backed by a limestone canyon just inland (3 dolmuş boats, daily mid-May to Oct 11am–6pm; TL15 return). Named after the many species that flutter about during the right seasons, it also holds a waterfall, 20min inland (TL5 admission). The beach itself is frequented by an uneasy mix of day-trippers sipping overpriced beers at the café, and New Age patrons attending regular yoga, Indian dance and healing seminars while staying in basic tent-or-bungalow accommodation (wthebutterflyvalley.blogspot.com).
