A Byzantine monastery complex carved into a cliff, set in a lush valley. The site is free, but May-Sept there's a 32 TL toll for cars on the access roads. There's a picnic area, pity about all the trash, and a couple of restaurants nearby.

A remarkable Roman double aqueduct above the village of Gümüşpınar. Here water from two catchments converged then flowed by an upper and lower channel all the way to Constantinople. In 2020 treasure hunters got it into their heads that gold was buried beneath, so they blew it up, incurring substantial damage..
Evcik Plajı
A wide, undeveloped sandy beach backed by cliffs, unexpectedly popular during summer weekends despite its relative remoteness. A narrow track steeply descends to it, but it's best to park your car ahead of the slope to avoid climbing back up in reverse. The ruins of the Byzantine church of St George over the bluff mark the northern end of the Anastasian Wall.
formerly Podima
The most interesting of the resorts along this part of the coast. The beach has multi-coloured stones much used as garden mosaics in the city. (Modern quarries nearby still extract these for the Turkish glass industry.) The town has restaurants and accommodation.
Çilingoz Tabiat Parkı
It has a sandy beach backed by forest where a creek runs out. This is as far as you can go in a standard car.
Korsan Koyu
A small and very isolated beach surrounded by rock cliffs.
A relatively developed beach.
