These two caves are located at the grounds of Grotto Bay Beach Resort in Hamilton Parish Bermuda. Cathedral Cave is marked by the large deep lake. The cave is lit up from inside. There is a platform from where you can view the cave. Or else you can take a plunge and swim in the lake, and see the beautiful cave from the waters. Prospero’s Cave is more spectacular of the two. It has dramatic formations of stalactites and stalagmites. It is believed that Prospero’s Cave was first discovered by Sir George Somers who came ashore by his ship Sea Venture in the year 1609. This is supposedly the first cave discovered in Bermuda. Prospero’s Cave is home to Natura Spa, and Cathedral Cave is available to Grotto Bay Beach Resort guests only.
