Just a few kilometres from the resort hotels of Kemer, Göynük Canyon cuts a 14-kilometre gorge through the Beydağları mountains, its walls rising 350 metres above a canyon floor just six metres wide. Inside, the outside world disappears entirely. The trail follows the course of a mountain stream through one of the most dramatic and accessible natural gorges on the Turkish Riviera, with sections of shallow water to wade through, sheer limestone walls on both sides and the narrow strip of sky visible far above. Optional activities including zipline, body rafting and canoeing add an extra dimension for those who want more than a walk. The tour is back at your hotel by 13:00, making it the perfect half-day adventure for those who want to see something genuinely extraordinary without losing the rest of the day.
