Excellent trip full of activity and history. Very enthusiastic and knowledgeable local guide who provided detailed information on the ruins that litter the region.
The activities were well organised and fun, with rafting down the canyon a highlight. The ruins of Termessos were also really impressive, with the remains of buildings poking out through vegetation. The hiking was fairly manageable, though the trails are fairly treacherous, full of loose stones and pebbles. I would recommended taking walking boots or hiking poles to reduced the risk of twisting an ankle.
The accommodation is my only concern with the trip. The hotel in Antalya is close to bars and pubs, with music until 1am. I would recommend bringing good quality ear plugs.
Overall a very good trip, albeit not necessarily the best value for money (but on the other hand that is true for most Much Better Adventure trips).
