Experience snorkeling at the famous wrecks spot know as The Aquarium. There you can find many tropical fishes and 3 beautiful wrecks (1 plane and 2 boats). From the Marina Taina you shall cruise until that spot, which is located inside the lagoon, in 10 minutes. There you will snorkel accompanied by the captain, for around 70 minutes, while admiring the tropical fishes and beautiful corals.
Afterwards you will return to the marina and you will receive pictures of your tour as a gift (note that the pictures will be sent to you by email at the end of the day).
