Swim with dolphins during your Virgin Islands vacation! Take the ferry from St John to Tortola island for a 45-minute dolphin encounter at Dolphin Discovery Tortola. Side-by-side with expert trainers, hop into the water to play with these amazing marine mammals. Spin around the playpen during a foot-push ride, and hold onto their fins and cruise through the water during a dorsal-tow — you'll be amazed by their thrilling displays of aquatic agility and grace. Numbers are limited to 10 during this personalized small-group activity.
