The Basics

Los Arcos is reachable only by boat, and most visitors arrive as part of a Puerto Vallarta day cruise that includes relaxing at sea and snorkeling in the caves of Los Arcos. The marine life is stupendously varied, from clown and puffer fish to rays and sea turtles. Sightseeing cruises typically also visit other must-see Puerto Vallarta attractions, such as the malecon (waterfront promenade), Romantic Zone, and Mismaloya Beach. There are also small-group snorkeling tours and popular South Shore private sightseeing cruises. Puerto Vallarta city highlights tours let you view Los Arcos from the shore and include hotel pickup and drop-off.

The best experience of our trip!
Cynthia was incredible and highly educated in the field of marine biology. We had the experience of a lifetime thanks to her. I’d come back again 1000 times!

Wonderful snorkeling and nature trip to Los Arcos and Mismoloya, followed by a boat ride along the gorgeous coast and inlets north of Mismoloya. Great adventure with nature guide Alissandro. Highly recommended.

Wild dolphins encounter & snorkeling at Los Arcos
Really fortunate to be the only couple on the trip, (2nd time with Viator that this has happened). Micheal (the guide) and Martin (boat driver) were great and very informative. When we found the dolphins in the bay we watched them for a while waiting for them to come close in to the boat, at which point we went for a swim with them. An amazing experience to have dolphins swimming around you within arm's length. From there we went to a snorkeling spot, again amazing lots of fish to see. Best of all on the run back to the marina we came across a pod of Orcas, apparently a rare occurrence and we followed them for a good half hour. Thoroughly recommend this trip

Things to Know Before You Go

  • Los Arcos is a must-see for nature and wildlife lovers, and first-time visitors to Puerto Vallarta.

  • Bring sunblock and a hat or sunglasses, as there’s little shade out on the bay. Also wear comfortable clothing, and tote a bathing suit, towel, and change of clothes.

  • Snorkeling gear is provided on most Puerto Vallarta boat tours; bring your own if visiting independently.

When to Get There

Los Arcos Marine Park is lovely year-round. Arrive early if you want to beat the crowds, especially during Puerto Vallarta’s high season (winter). Spring and fall strike a nice balance between pleasant weather and manageable crowds. Wet weather is likely from July through September.

Mismaloya Beach

A small sandy beach on a picturesque jungle-fringed cove, Mismaloya sits just south of Puerto Vallarta along the coast of Banderas Bay. In 1964, John Huston’s movie The Night of the Iguana put this now-famous beach town on the map. A popular day trip from Puerto Vallarta, it offers several seafood restaurants, thatched-roof palapas, and one large resort.
