The trip to Uzungöl (Long Lake) is the second most popular excursion out of Trabzon, after Sumela. Were it not for the mosques, you could be in Switzerland. The scenic lake, at just under 1100m, has a bazaar district around its outlet and is best seen by renting a mountain bike from one of the teashops.
Uzungöl makes an ideal base for rambles southeast up to the nearby peaks of Ziyaret (3111m) and Halizden (3376m), with a chain of glacier lakes at the base of the latter. It’s a very long day’s hike there and back – though you can go partway by car to save time – so take a tent and food for two days if at all possible.
