The St. Croix Environmental Association (SEA) invites people to register for an advanced snorkel clinic. ID is required and space is limited. There is no charge for SEA members and children (only experienced snorkelers please). $10 for non-members. Because winter sea conditions are unpredictable, SEA will decide the location for the snorkel a few days before the actual date. Snorkelers are welcome to bring their own gear or they can borrow masks, snorkels, fins and vests from SEA.
