Los Arcos de Mismaloya: complete guide

If you come to Puerto Vallarta and only have time for one adventure at sea, make it this one. Los Arcos de Mismaloya is the bay's underwater icon: a cluster of rocky islets sculpted by the waves, sunlit caves and water so clear you'll spot the fish without lifting a finger. In this guide we tell you what they are, what you'll experience, how long it lasts, how much it costs and how to make the most of the Los Arcos Tour.

What are Los Arcos de Mismaloya?

Los Arcos is a protected natural landmark located off Mismaloya Beach, just minutes south of Puerto Vallarta. It's a group of rock formations that rise out of the sea and that, over the centuries, the water has carved into natural arches and tunnels — hence the name (arcos means arches). Because of its immense ecological value, the area is designated a protected natural zone, which has helped preserve extraordinarily rich marine life right below the surface.

That very protection is what makes the Los Arcos tour so special: swimming here means snorkeling at one of the best spots in all of Banderas Bay, in a well-cared-for setting teeming with life.

What you'll see on the tour

The trip takes you around the five islands that make up the landmark and through its three natural caves, where the light filters in and the water turns incredible shades of blue. Once you slip on your snorkel gear you'll see why this place is so famous: schools of colorful fish, rock formations that plunge steeply underwater and visibility that, on a good day, feels like an aquarium.

For those looking for a little adrenaline, there's time for the classic cliff jump into the sea — one of the most requested photos of the day. And if you're a movie buff, you'll love knowing that these waters were the setting for the film "The Night of the Iguana", the 1960s shoot that put Puerto Vallarta on the world map.

Duration, price and what's included

The tour lasts about 1 hour and 20 minutes — enough time to cruise out to Los Arcos, enjoy the snorkeling and head back without rushing. The price is $500 MXN per person, and children under 3 go free.

It includes an onboard guide, life jacket and snorkeling gear, so there's nothing special you need to bring — just your urge to jump in the water. If you'd like to see the boats you'll be sailing on, take a look at our fleet, comfortable and equipped to keep the experience safe from start to finish.

Best times to go

Early morning usually brings the calmest sea and the best visibility, plus a gentler sun for comfortable swimming. Mid-morning tours also work great and often line up with the best light for photos inside the caves. In general, weekdays are less crowded than weekends, when the site draws more local visitors.

Like any activity at sea, conditions depend on the weather that day. That's why it's best to confirm your time when you book; we'll gladly recommend the best departure for the date of your visit through our contact page.

Practical tips

Apply biodegradable sunscreen before boarding to protect your skin and, above all, the marine ecosystem. Bring a towel, water to stay hydrated and, if you have one, an underwater camera or a waterproof phone case — you'll want to capture it all. If you're not a strong swimmer, don't worry; the life jacket keeps you afloat and the guide always keeps an eye on the group.

One last tip: relax and enjoy. Los Arcos is one of those places best savored slowly, floating face down and letting the fish come to you. If this taste leaves you wanting more sea, the South Beaches Tour is the perfect next step: a longer trip that combines Los Arcos with the beautiful hidden beaches along the bay's southern coast.
