The #1 best-rated excursion in Sayulita Mexico is the Marietas Islands on a high-powered catamaran with Ally Cat Sailing Adventures! Our travel family had so much fun on this day cruise to the Marietas Islands off the coast of Puerto Vallarta. We got to swim, snorkel, jump off the boat, SUP, and kayak all in a day! The Fat Cat boat was a blast, we even got to see the rare blue-footed booby bird. The crew, accommodations, food, and activities made Ally Cat Sailing Adventure our top choice for an overall excursion in Sayulita Mexico. We've been on several snorkel excursions before, this was one of the best! Subscribe and join us in more Escaping The Bubble adventures! Escaping the Bubble Travel Vlog video.
