Moaning Caverns and Mercer Caverns also provide guided tours that are generally suitable for various ages.

Accessibility varies significantly by cave. Many developed caverns like Mercer Caverns and Moaning Caverns have stairs, viewing platforms, and lighting for easier access. However, natural caves or more challenging explorations, such as CuevaDelNispero (which is noted as challenging), may involve uneven terrain, narrow passages, or require specific gear. It's always best to check the specific accessibility details for each cave before visiting.
