If you want to go snorkeling with all the amenities you need, I would highly recommend going with the Pride of Maui tour. They take you out to secluded coral reefs for an hour of water time. It's followed up by a BBQ meal and an open bar. It's 3.5 hours round trip and so worth it! They provide SPF 50 reef-safe sunblock (free of charge) as well. Snorkeling equipment is included! We had a blast and the ship crew were so friendly and knowledgeable.
