A sort of underground Pamukkale, this cave gushes with calcium- and sulphur-rich water. The flow, into a large sinkhole, creates a bright, white pyramid with warm travertine pools below. Bathing is allowed in the non-aesthetic outside pool.
Kaklık Mağarasi is 35km from Pamukkale. Visiting on a tour from Pamukkale is easier than public transport, but the frequent dolmuşes and buses heading east from Denizli on the highway can drop you in Kaklık village (TL5), 4km south of the cave. A sign points the way from there – walk the shadeless road or flag down a farm vehicle.
En route to the cave from Pamukkale, Ak Han (circa 1251) is a well-preserved Seljuk caravanserai with a beautifully carved gateway.
