Just south of Puerto Vallarta, Los Arcos de Mismaloya rises from Banderas Bay as a cluster of granite islets, caves, and sea arches. This half-day snorkeling tour gives visitors a simple way to experience the area without arranging transport, gear, or a private boat.
A short trip from the city to one of the bay’s best-known natural landmarks
Puerto Vallarta has no shortage of boat tours, but Los Arcos remains one of the easiest marine excursions for travelers who want something active without committing to a full-day outing. The protected marine area lies off the coast near Mismaloya, south of the city, where granite rock formations rise from the water, creating caves, arches, and sheltered areas for marine life.
The GetYourGuide activity, listed as Puerto Vallarta: Los Arcos Islands Boat Tour and Snorkeling, is a 3.5-hour guided tour offered in English and Spanish. The experience begins in the old center of Puerto Vallarta, where guests meet the guide before taking a public bus toward Mismaloya. From the beach, the group boards a boat for the ride to Los Arcos.
What makes Los Arcos worth visiting

Los Arcos de Mismaloya is one of the most recognizable natural features in Puerto Vallarta. The area is known for its five rocky islets, sea caves, reefs, and birdlife, making it a popular place for snorkeling, diving, kayaking, and paddleboarding. Puerto Vallarta’s official tourism guide describes Los Arcos as a habitat for marine birds, including blue-footed boobies, parrots, and pelicans, while the reefs below support fish and other sea life, such as puffer fish, stingrays, and octopuses.
The setting is also close enough to the city that visitors do not need to spend hours in transit. PuertoVallarta.net places Los Arcos in the South Zone of Puerto Vallarta, near Mismaloya, roughly 7 miles (about 20 minutes) from the main square by road. The site notes that the formations should not be confused with the decorative arches on the Malecón in downtown Puerto Vallarta.
What the tour includes
The tour is designed as a guided, low-hassle way to reach the marine park. According to the activity page, the experience includes a guide, a bus ticket, a boat trip, snorkeling gear, and a life vest. The activity page also says guests should bring a towel, sunscreen, and water.
Once the group reaches Mismaloya, the boat heads out toward the islands. The guide shares information about the flora and fauna of Los Arcos, while the captain brings guests into areas where they can see the rock formations and natural caves. The tour also includes time to snorkel in a designated area where visitors may see fish and coral, depending on conditions.
Snorkeling, caves and birdlife

For many visitors, the main draw is the chance to snorkel without needing to organize a separate boat rental. Los Arcos is one of the better-known snorkeling spots in Puerto Vallarta because of its mix of rocky habitat, underwater features, and marine life. The GetYourGuide listing describes the tour as a visit to the five islands of Los Arcos National Marine Park, with time to explore caves, see nesting birds, and snorkel in the bay.
Travelers should keep expectations flexible. The activity page notes that visibility and currents can vary, which may affect how many fish guests can see. This is normal for ocean-based snorkeling tours, especially in areas where weather, currents, and seasonal conditions change from day to day.
A stop tied to Puerto Vallarta’s tourism history
The tour also includes a visit to an iconic location tied to Puerto Vallarta’s history. That context likely points to Mismaloya, the coastal community long associated with the filming of The Night of the Iguana. The 1964 John Huston film is widely credited with helping bring international attention to Puerto Vallarta, particularly because of its Mismaloya location and the publicity surrounding the production.
This historical layer gives the trip more than just a snorkeling angle. Visitors get a look at the coastline that helped shape Puerto Vallarta’s rise from a smaller fishing town into one of Mexico’s best-known Pacific beach destinations.
Who this tour is best for
This activity is a good fit for travelers who want a shorter excursion, first-time visitors who want to see Los Arcos without planning their own transportation, and people who prefer having a guide handle the logistics. It may also appeal to travelers staying in central Puerto Vallarta or the Romantic Zone, since the route begins in the old center and uses the local bus to reach Mismaloya.
It is not the right choice for everyone. The activity page says the tour is not suitable for children under 8, people with mobility impairments, or wheelchair users. Travelers who are uncomfortable entering the water, climbing in and out of small boats, or dealing with variable sea conditions may want to consider a sightseeing-only boat tour instead.
Practical tips before booking
Check the starting time before reserving, since the activity page lists the duration as 3.5 hours and advises checking availability for exact departure times. Guests meet near the OXXO by the white-and-green buses to Mismaloya, and the instructions specifically say not to board the bus alone or enter the nearby tour shop, which belongs to a different company.
Bring a towel, water, and reef-conscious sun protection. It is also smart to wear a swimsuit under light clothing, use sandals or shoes that can get wet, and carry only what you need. Since the tour uses public transport and a boat from Mismaloya, travelers should be ready for a casual, local-style outing rather than a resort-style excursion with hotel pickup.
A simple way to experience Los Arcos
Los Arcos is one of Puerto Vallarta’s signature natural sights, and this tour gives visitors a manageable way to see it from the water. The combination of public bus, beach departure, boat ride, caves, birdlife, and snorkeling makes the experience feel connected to the everyday rhythm of the south shore.
For travelers who want a half-day activity with nature, light adventure, and a bit of local history, a guided Los Arcos snorkeling tour is one of the most straightforward ways to get beyond the beach and into the bay.
