Experience the Marietas Islands: Snorkeling & Hidden Beach Tour

In Puerto Vallarta, the Marietas Islands offer a captivating blend of crystal-clear waters, vibrant marine life, and a famous Hidden Beach accessible only to those prepared for a bit of adventure. This 5-hour snorkeling excursion is led by knowledgeable guides, often naturalists, who make sure you get the most from your day. For $120 per person, you get a boat trip, gear, a boxed lunch, and the chance to explore one of Mexico’s most unique protected areas.
What we really love about this tour is the small group size, which allows for personal attention and a more relaxed experience. Plus, the focus on wildlife and conservation adds a meaningful layer to what could otherwise be just another day in the sun. The guided instruction ensures even less experienced snorkelers feel comfortable in the water, and the chance to visit Hidden Beach—albeit with restrictions—makes this trip memorable.
A word of caution: access to the Hidden Beach isn’t guaranteed—it’s subject to government permits, weather, and demand—so if your heart is set on stepping onto this iconic sand spot, be prepared for some luck and patience. Also, visitors must be able to swim 200 meters to qualify for entry. This tour suits active travelers who appreciate nature, enjoy snorkeling, and are open to some unpredictability in their plans.

The Basics of the Marietas Islands Snorkeling Tour

If you’re contemplating this trip, here’s what you need to know upfront. The tour is approximately 5 hours long, starting from the Marina Vallarta, where you’ll check in with your guide, typically a biologist or naturalist. The price is $120 per person, which covers the snorkeling equipment, lunch, bottled water, and guiding. Keep in mind, the admission to the Islands costs $10, and there’s a port fee of $3—these are paid on-site or included in the fee, but it’s good to be aware.
The tour emphasizes a small group experience—usually no more than 10 travelers—which means you’ll probably have more space, a more personalized guide, and better chances to see wildlife up close. Some reviews mention the trip being very well-organized, with guides like Maggie and Cynthia earning praise for their knowledge and friendliness.
Itinerary in Detail: What to Expect
Stop 1: Marina Vallarta
The trip begins here, with check-in at the Ecotours Vallarta office or dive shop. It’s a quick, straightforward process, and you’ll meet your guide, who will brief you on safety and the day’s plan. The importance of this initial step cannot be overstated—clear communication here sets the tone for a smooth experience.
Stop 2: Marietas Islands
The boat ride to the islands takes approximately 3 hours, giving plenty of time to relax, enjoy the scenery, and keep an eye out for dolphins or whales—many reviewers mention seeing these marine mammals along the way. The boat itself is described as calm and comfortable, often with a friendly crew eager to share their local knowledge.
Once at the islands, the focus is on snorkeling, with your guide leading small groups to prime spots, where visibility tends to be excellent—many mention the crystal waters and spectacular fish sightings. You’ll have the chance to explore beaches and rocks, with some guided walks on the islands available if time permits.
Visiting Hidden Beach
The moment everyone hopes for is a visit to Hidden Beach—a small, secluded cove with a sandy floor, framed by rocks and accessible by boat or swimming through a tunnel. However, access is limited, and guides have to secure permits, so there’s no guarantee every group will get in. Some reviews mention that the guides do their best, but weather and demand can prevent entry.
Visitors must be aged 10 to 65 for the Hidden Beach, and only about 10 minutes are allowed on the shore. During this time, you’ll wear helmets and life vests, and you’ll need to be comfortable swimming and climbing a ladder to leave the boat. If you don’t get a spot, you’ll spend that time on the boat, enjoying the scenery or wildlife.
Snorkeling & Wildlife
The snorkeling is often the highlight. With gear included, you can float over vibrant underwater life, including colorful fish, sea turtles, and sometimes nurse sharks. Reviewers mention fantastic visibility and a vibrant ecosystem. Guides like Maggie often share insights about the birds and marine fauna, enriching the experience.
Lunch & Return
A simple yet satisfying boxed lunch—sandwich, fruit, and snacks—keeps you fueled for the day. After about 3 hours exploring and snorkeling, the boat heads back to Puerto Vallarta, often with the chance to spot whales or dolphins if the season permits. The trip concludes at the marina, where you can relax or explore local shops.
Authentic Experiences & Honest Insights

One of the most appreciated aspects of this tour is the knowledgeable guides. Many reviews praise guides like Maggie for being extremely caring and informed. Guests love the way guides explain the flora and fauna, making the trip educational as well as fun.
The small group size and focus on wildlife make this a good choice for travelers who want a more intimate connection with nature, rather than a crowded tourist boat. The conservation emphasis resonates with many, as it adds a sense of responsible tourism.
However, some travelers have expressed disappointment about the inability to guarantee access to the Hidden Beach. Weather, demand, and permit availability can change plans unexpectedly. This unpredictability can be frustrating if your priority is to step onto that sandy spot, but it’s important to understand that such restrictions are outside the tour operator’s control.
The cost of $120 per person is reasonable considering the included gear, lunch, and guided experience—many agree it offers good value, especially given the rarity of the wildlife encounters and the scenic boat ride.
Practical Tips for Your Trip

- Bring a towel and waterproof camera to capture the scenery and wildlife.
 - Dress in light, quick-drying clothing; the boat ride can be chilly if it’s windy.
 - If you’re not a strong swimmer, consider wearing a life vest at all times.
 - Arrive early at the marina for check-in, especially during busy seasons.
 - Be prepared for possible waiting or missed opportunities to visit Hidden Beach—patience is key.
 - Remember, drones are prohibited in the park, so leave the drone at home.
