I've used caverns many times in outdoors adventures I've created. Extensive natural cave systems are rare, so in my games they're often small and are just part of an adventure. I'll write next time about my 4- or 5 facet structure for designing outdoors adventures and how the parts fit together.

Occasionally caverns are bigger— and exotic. I've designed two adventures that were in volcanoes. In one the PCs had to enter through a natural lava tube. Beyond that they found a series of chambers that were partly natural and partly monster-made. And it was HOT inside from natural lava fissures.

A cenote would make a great setting. I haven't used one, though from having swam through one in Mexico several years ago I'm already starting to imagine how novel it could be. To make it suitably challenging for PCs, not tourists, there could be a family of shocker eels in the water and stirges, not bats, in the cave.
