More ways to explore the area's outdoor wonders
You step off an air-conditioned van onto loam-soaked forest, the humidity pressing like a warm hand. Guides fit helmets and headlamps, voices low as the trail bends toward a river that grinds a soft, steady sound through the understory. The hike to Actun Tunichil Muknal (ATM) begins as a walk through secondary rainforest — ferns brushing knees, motmots calling in the canopy — and becomes a passage through time when the water parts and the cave swallows you.
