The entrance gate sits low against a scrubby limestone escarpment; damp air from the cavern breathes out as the group moves from sunlight into a dim, cool world. On the Río Secreto Plus half-day tour, travelers step into soaked caverns where lamp light drags shadows across stalactites and an underground current dares you onward.

Even if water shoes are provided, bring or request rubber-soled water shoes for traction on slick limestone.
Hydrate before and after
The humid cave environment is cool but physically demanding—drink water before arrival and after the activity.
Arrive early
Morning departures reduce heat exposure between activities and often mean smaller groups at the reserve.
Quick-dry base layer
Lightweight clothing under the wetsuit prevents chafing and dries quickly after the cave portion.
