Deep in the Gürleyik hills 10km northwest of Safranbolu, the impressive Bulak Mencilis Mağarası cave network opened to the public a decade ago, although troglodytes may have lived here many millennia before that. You can walk through 400m of the 6km-long network, enough to reveal a fine array of stalactites and stalagmites with inevitable anthropomorphic nicknames.
There are steps up to the cave and you should wear sturdy shoes as the metal walkway inside can be slippery and wet.
A taxi from Safranbolu costs ₺40 return.
