The Crystal and Fantasy Caves in Bermuda offer a captivating subterranean experience with stunning crystal formations and clear underground pools. Accessibility can be limited due to stairs and narrow passages, so it's advisable to inquire about specific needs in advance. While solo visits are possible, guided tours enhance the experience by providing geological insights and historical context. The caves are generally open year-round, but it's best to check for seasonal closures or weather-related restrictions. Expect to spend approximately 1-2 hours exploring the caves, and the cost typically ranges from $20 to $35 per person. Comfortable shoes are recommended due to the uneven surfaces and steps.
