More ways to explore the area's outdoor wonders
Dawn strips the jungle to silhouettes as guides stoke a small fire at the lip of a cavernous sink; the smell of damp limestone and earth fills the air. From the trailhead in the foothills of the Maya Mountains, the approach climbs roughly 90 minutes to the rim of Actun Loch Tunich where a 300‑foot Black Hole Drop yawns beneath you. Helmets click, harnesses cinch, and the cave pulls you down into a cool, echoing world where rimstone dams pool and crystals glitter like old coin.
