Hi there,
Most of the guided excursions that involve snorkeling in Punta Cana will last a few hours, and if you don’t already have snorkeling equipment, it will be provided for you.
Kids usually pay half-price to snorkel in Punta Cana, which is good if you are traveling with kids.
Soft drinks are generally offered to guests on the
snorkeling boats for shorter trips, and snacks and/or a meal are typically provided on longer excursions.
Things that you might bring along with you when booking a Punta Cana
snorkeling excursion include sunblock and some towels.
It’s also not a bad idea to bring a waterproof camera so you can take some shots of the coral and the different fish that you see. The clarity of the water off the Punta Cana coast makes for good visibility, so you can get some really nice shots.
hope this helps
