Sian Ka'an boat tour from Tulum: Snorkel the barrier reef

Spend a full day on the water without arranging the logistics yourself

A full-day boat tour of Sian Ka'an Biosphere Reserve departing from Tulum, with snorkeling on the barrier reef, a visit to a natural sandbank, and lunch in the fishing village of Punta Allen. The tour includes hotel pickup, a local guide, snorkeling equipment and a 10-hour itinerary that covers the reserve's coastal lagoons and marine ecosystems. Sea conditions determine whether snorkeling happens on any given day, and the tour may be cancelled in bad weather.

The Experience

What makes Sian Ka'an worth the drive? It's one of Mexico's largest protected areas, and the only real way to see it is by boat. The day starts with hotel pickup in Tulum and a 30 to 40 minute drive on an unpaved road to the reserve entrance—rough enough that the operator calls it an adventure. A guide gives an introductory overview of the biosphere before you board the boat to explore the coastal lagoons and marine ecosystems where dolphins, manatees, sea turtles, birds and thousands of reef fish live.

If sea conditions allow it, you'll snorkel on a section of the barrier reef system. The snorkeling is not guaranteed—weather and water conditions decide whether it happens—but when it does, you're in the water among the species that make the Mesoamerican reef one of the region's defining features. After snorkeling, the boat takes you to a sandbank locals call "nature's swimming pools," where you can swim and rest. The day ends in Punta Allen, a small fishing village at the tip of the peninsula, where you have lunch and time to walk around before the return to Tulum.

The tour runs 10 hours total and stays under 12 people per group. A live guide speaks English, Spanish, Italian or French. You get snorkeling equipment, a life vest (mandatory on all boat tours), fruits, water and snacks throughout the day. Hotel pickup and drop-off in Tulum are included; if you're staying north of Tulum—between Conrad and Puerto Aventuras, or further toward Cancun—there's an extra fee per person depending on your location.

Top questions

What's the snorkeling actually like in Sian Ka'an?

Snorkeling happens on the barrier reef system if sea conditions permit, and you'll be in the water among thousands of aquatic species. The snorkeling is not guaranteed on any given day because weather and water conditions can change, and the tour may be cancelled altogether if conditions are unsafe.

How rough is that unpaved road to Punta Allen?

The road is bumpy enough that the operator describes it as part of the adventure. You'll drive on it for 30 to 40 minutes after entering the biosphere reserve, so expect a genuinely rough ride, not a minor detour.

What do I need to bring on this tour?

Bring a towel, bathing suit, comfortable shoes, an extra shirt, hat, sunglasses and a camera. Cash is essential because most local vendors in Punta Allen only accept it. Biodegradable sunscreen and mosquito repellent are optional but recommended.

Is hotel pickup included from anywhere in the Riviera Maya?

Hotel pickup and drop-off in Tulum are included. If you're staying north of Tulum—between Conrad Tulum by Hilton and Cancun—there's an extra fee per person that varies by location, ranging from $10 to $45 USD depending on how far north you are.

Can children go on this tour?

Children as young as 6 years old can join, but they must be accompanied by an adult at all times. The tour is not recommended for pregnant women or travelers with spinal injuries, poor cardiovascular health, or less than moderate physical fitness.

What happens if the weather is bad?

The tour may be cancelled if weather conditions are unsafe. Snorkeling is also dependent on sea conditions and may not happen even if the tour runs. You should check your confirmation email for the pickup time and be prepared for a full-day commitment.
