I don't normally do horse excursions, but as it was so cheap, i booked it-through excursionsmarmaris-£10 i think.
The trip is about 3 hours, though you only ride for about 30 minutes. To be honest though, i really enjoyed this trip. The group i was with was fun, and the horses were fab. Going through the river was the best bit. The horses were well behaved and perfect for beginners, though hold on at all time's, as my horse shot off on a couple of occasions. It's the usual selling of photos at the end, and although i wouldn't do this trip again, i would recommend it.
