Karadere

Only about 20km/12.5mi north of Bolu a good forestry road leads into one of those remote forested Pontic mountain valleys which tourism has so far left unscathed. There are no villages in the 40km/25mi-long Karadere valley with its bubbling mountain streams, only a forestry office. This makes a good starting point for hill walks through the jungle-like mixed forests of the valley and surrounding area. Bolu, for example, is over the ridge to the south and can be reached comfortably in a day.
