Marietas Islands: Hidden Beach Snorkel Tour & 99% Entry

Summary

Swim into Marietas Islands’ secret beach with expert guides and rare wildlife

You’ll set off by boat from Marina Vallarta, watch dolphins at sunrise, then snorkel crystal waters around Marietas Islands with a local guide before swimming into the surreal Hidden Beach itself. Expect fresh fruit snacks, conservation-minded touches, and real stories from your guide—all with official permits included.

What’s the experience like?

The first thing I remember is the sound of the boat’s engine fading as we left Marina Vallarta behind—just this salty breeze on my face, pelicans gliding low over the water. About ten minutes in, our guide Ana pointed out a pod of dolphins playing at the mouth of the Ameca River. I didn’t expect to see them so soon, honestly. Everyone got quiet for a second, just watching their fins slice through the morning light. It felt like we’d already gotten our money’s worth and we hadn’t even reached the Marietas Islands yet.

The ride out took about an hour but it didn’t drag—Ana kept telling us stories about the islands’ volcanic past and why they’re so protected now. She handed out apples and bananas (no plastic anywhere, which I liked), and reminded us to fill our reusable bottles from the big jug onboard. There was a bit of wind that day; you could taste salt on your lips and feel spray on your arms. When we finally anchored near the islands, she helped us with our snorkel gear—mine kept fogging up but she showed me this trick with spit (gross but it worked). The water was colder than I expected but clear enough to spot these electric-blue fish darting around.

Getting to the Hidden Beach is kind of wild—you swim through this short tunnel carved into rock while waves echo all around you. My heart was thumping like crazy (I’m not exactly an Olympic swimmer) but Ana swam ahead, waving us in with this big grin. Once inside, sunlight poured through the hole above and everything went quiet except for seabirds overhead. I just lay back in the sand for a minute trying to take it all in. The place feels both tiny and enormous at once—you know? I still think about that view when things get noisy back home.
