Profile and sections
Sac Pepem is one of the shallow cave systems near Muyil. The name means ‘white butterfly’. Natalie Gibb, Anders Knudsen and Vincent Rouquette-Cathela were its first explorers; in 2016 it was 1,940 m long, with four cenotes. QRSS now puts Sistema Sac Pepem at 7,084 m, down to -14.6 m, with ten cenotes (Jan 2025).
In 2016 PSAI also listed Sistema Kiix Pepem (‘thorny butterfly’) west of Muyil, 2.2 km and -13.4 m, with five cenotes, one of them called Sac Pepem. Whether that system now belongs to Sac Pepem is not published.
Practical: there is no cavern diving in Muyil, only cave diving (PSAI, 2016). Arrange this cave through a dive centre that works there.

How to get there
On ejido Chuyaxché land near Muyil; who owns the entrance is not published. Not a walk-in site: Under the Jungle (Tulum) lists Sac Pepem as one of its own projects that needs special access and advance planning. In 2016 the Muyil caves were paid with a day fee at the Diconsa opposite the ruins. No map pin known.
