Actun Tunichil Muknal

Family at ATM Cave

Actun Tunichil Muknal (Cave of the Crystal Sepulchre), is one of the most impressive and artefact-rich Maya ceremonial caves ever found, containing rare bloodletting altars used in sacrifices by Maya royalty and over 1400 catalogued artefacts as well as sacrificial human remains. The ATM Cave is home to the famous “Crystal Maiden” the intact skeleton of a young female that, due to a covering of calcium carbonate, sparkles eerily in the lamp light.

This is a wet cave – you swim into the mouth and then wade through ankle to chest high water before climbing to a labyrinth of dry chambers which lead to the cathedral-like main hall, a towering chamber 350 metres in length and 50 mteres wide and filled with artefacts and sacrificial remains. After this another climb takes you to the stone sepulchre (after which the cave is named) where the Crystal Maiden lies.
