Fluorescent snorkeling with ultraviolet flashlights

Blue Horizon Diving is the only diving school on Koh Phangan that offers fluorescent snorkeling and diving activities. We have professional and specific equipment: ultraviolet diving lamps and masks with yellow filters to accentuate the phenomenon of fluorescence. You will also have the appropriate diving or snorkeling equipment as well as a wetsuit. We have been practicing this activity for almost 10 years and are happy to share our experience with you. This fascinating activity, accessible to all, is practiced at night. During the activity, divers and snorkelers can experience the reefs of Koh Phangan in stunning fluorescent colors thanks to a natural reaction of corals with ultraviolet light. Thanks to our experienced guides, you will discover in exclusivity this phenomenon of coral fluorescence which is very little known and practiced.
