A fascinating boat ride through the flooded workings of an 18thC lead mine. The boat trips are fully supervised by experienced guides and take you deep inside a limestone hill to the 'bottomless pit', a huge underground lake in the natural Speedwell Cavern. Speedwell Cavern is an excellent venue for educational visits. We cater for all age ranges from Key Stage 1 through to GNVQ level. Special rates are offered for pre-booked groups, and a special "joint ticket" is available for groups wishing to visit both Speedwell Cavern and Peak Cavern. Speedwell has a large room available for school project work, meetings and as a lunch room on wet days .
