A real underwater adventure is just around the corner on this full-day snorkelling tour. You'll head to two different spots within the Puerto Morelos National Reef Harbour for some guided snorkelling. At each reef, you'll have about 45 minutes to swim, explore and check out all the marine life that calls these areas home. After your time in the water, you'll head to a restaurant called Casa Matea for lunch, before some free time to do some shopping. Just so you know, the drinks aren't included at lunch.
