Crystal Cave
A marble cave whose guided route passes stalactites and curtain formations, with steep canyon trails outside.
Formed by the dissolution of marble, the cave features stalactites, draperies and an underground stream. Visits are by guided tour only. The standard tour lasts about 50 minutes, and tickets must be booked online in advance, as none are sold on site. From the General's Highway, a narrow mountain road of about 11 kilometers leads to the site, followed by a steep walk of about 800 meters downhill to the entrance. The cave stays at around 10°C year-round, so bring a jacket. Crystal Cave has closed at times in recent years due to wildfires and road repairs, so check the national park website before you go.
