Devil’s Den is a privately owned SCUBA diving training facility that allows snorkeling. The Den is a pre-historic underground cave that is only accessible via narrow stairs that end underwater. Therefor the only admission to the Den its self is for people who are snorkeling or SCUBA diving and by definition are good swimmers. Children under the age of 6 and any type of flotation device are not permitted in the Den. To maximize the guest experience they limit the number of snorkelers to 35 at a time. On busy days this can create a wait time of several hours. Please visit their devilsden website for a complete description and pictures of their venue.
