Spend a full day on a catamaran from Puerto Vallarta to the protected Marietas Islands—snorkel rocky reefs, paddle around volcanic arches, and relax with an open bar on the return. Practical and social, this trip mixes active water time with onboard comfort.
More ways to explore the area's outdoor wonders
You step onto the catamaran as the city falls away—a line of white wake, a band of sea-glass between you and the islands. Salt and citrus mingle on the breeze while the crew hands out hotcakes and juice; the hull answers the swell and the Marietas rise like sculpted rock from the Pacific.

Duration
10 hours
Fitness Level
Suitable for people comfortable sitting on a boat for several hours and for short periods of paddling or snorkeling; basic stamina for repeated entries into the water is helpful.
Wildlife
History
The Marietas were shaped by volcanic rock and later altered by 20th-century military target practice; those impacts helped form some of the islands’ unusual beaches and caverns.
Conservation
The islands are a national marine park with visitor limits and regulations—use reef-safe products, follow guides’ instructions, and avoid touching coral or wildlife to minimize impact.

Bring cash for the SEMARNAT bracelet
A park access fee (around $10 USD) is usually collected on-site and is easiest to pay in cash—keep small bills handy.
Use biodegradable sunscreen
Protect reef life by applying reef-safe sunscreen before you board—reapplication on the boat is easier than in the water.
Time your meds for seasickness
If you get queasy, take prevention an hour before departure; morning legs are often calmer for snorkeling.
Lock valuables in a dry bag
Bring a small dry bag for phones and documents—deck movement and splashes are common when boarding small pangas.
Swimsuit & quick-dry towel
You’ll be in and out of the water; quick-dry fabric and a towel make transitions fast.
