We have on board snorkel masks and fins. But keep in mind that around 20 different people per month use the same equipment daily. Maybe it will not be in same conditions as your personal equipment that you use twice a year. Or could happen that the whole group wants snorkel at the same time and maybe we won't have enough equipment for the entire group. For that reason, if snorkel is on your priority list, feel free to bring your personal equipment. We bet you won't regret!
