Akumal: Snorkeling with Sea Turtles and What Else to Know
By Mr. Playas · Updated 2026
Akumal is a small bay town about 100 km south of Cancún on Highway 307, between Playa del Carmen and Tulum. It is not particularly interesting as a town. It is extremely interesting underwater. Akumal Bay has one of the densest resident populations of green and loggerhead sea turtles accessible from a beach anywhere in the Caribbean — you wade in, put on a mask, and within a few minutes you will likely be in the water with turtles. No boat required.
Snorkeling with Sea Turtles
The turtles in Akumal Bay feed on seagrass beds in 2–4 meters of water. They are accustomed to human presence and tend to move slowly and stay in the bay. Sighting rates are very high — not guaranteed, but on most days, most people who spend an hour in the water will see at least one, often several.
The best area is the center of the bay and slightly to the left (south) of the main beach entrance, where the seagrass is densest. Snorkel equipment is available from multiple rental shops near the beach entrance for $10–15 USD. A life jacket is required for entry to the protected zone — this is enforced by the volunteer guide team stationed at the beach.
You are required to follow basic wildlife interaction rules in the water: no touching, no chasing, maintain distance. Guides on the beach enforce this, and the volunteer team (Centro Ecológico Akumal) runs an education station at the entrance explaining what you'll see and the rules of engagement.
Akumal Bay is one of the most visited snorkel spots on the Riviera Maya. From 10 AM to 2 PM the water is crowded enough to diminish the experience — both for you and the turtles. Early morning produces the best light, calmer conditions, and significantly fewer people. The turtles are in the water all day. .
Akumal Bay vs Half Moon Bay
There are two snorkeling areas in Akumal: Akumal Bay (the main beach, directly off Highway 307) and Half Moon Bay, about 700 meters north. Half Moon Bay is accessed via a small road and tends to be significantly less crowded. It has fewer turtles than the main bay but better coral and more reef fish — eagle rays, nurse sharks, and triggerfish are common.
For turtle encounters: Akumal Bay. For reef quality and fewer people: Half Moon Bay. For both: arrive early, hit Akumal Bay first, then walk north to Half Moon Bay.
Cenote Dos Ojos — 5 Minutes from Akumal
Cenote Dos Ojos (Two Eyes) is approximately 5 km north of Akumal off Highway 307. It is one of the most accessible entry points into the Dos Ojos cave system — the world's longest known underwater cave network. Two open-air cenote pools connected to the cave system allow snorkeling in crystal-clear freshwater with stalactites visible above and below the waterline. Admission: $20 USD. Snorkel equipment rental: $10 USD additional. Scuba diving is also available here for certified divers. This is a natural combination with an Akumal turtle morning — two completely different underwater environments in the same half-day.
Getting to Akumal
Akumal is directly on Highway 307, well-signed. By car from Playa del Carmen: 35–40 minutes south. By car from Tulum: 20–25 minutes north. By car from Cancún: approximately 90 minutes.
The ADO bus stops at the Akumal exit on Highway 307 from both Cancún and Tulum — it is then a 1 km walk or $3 taxi ride into the bay. Collectivo vans (shared minibuses) run Highway 307 between Playa del Carmen and Tulum for $2–4 USD and will drop you at the Akumal junction on request. Car rental gives you the flexibility to combine Akumal with Dos Ojos and any other stops along the highway.
Day Trip vs Staying Overnight
Akumal works best as a half-day or full-day trip from Playa del Carmen or Tulum. The town itself is small — a handful of restaurants, a dive shop, and a few hotels. There is not enough to fill more than a day here unless you are diving multiple sessions. The appeal is the snorkeling and the natural setting, not the town. Base yourself in Playa or Tulum and come for the morning.
Diving in Akumal
Akumal Dive Center is one of the longest-operating dive shops on the Riviera Maya. Reef dives depart from the bay; cave diving trips go to Dos Ojos and the surrounding cenote system. A two-tank reef dive runs $80–110 USD. Cave diving requires Open Water certification minimum; a guide and dive light are mandatory. Full-day dive packages combining ocean reef and cenote cave diving are a popular option for certified divers.
Frequently Asked Questions
For snorkeling with sea turtles: yes, unambiguously. It is the most accessible turtle snorkeling experience in the Riviera Maya and one of the best in the Caribbean. As a destination in itself for more than half a day: limited — the town is small and the other activities are the surrounding cenotes, not Akumal itself.
Not guaranteed but very reliable. On most mornings, most snorkelers see turtles. The population is resident, not seasonal — turtles are present year-round. Early morning arrivals (before 9 AM) have the highest encounter rates.
No. You can walk in independently, rent equipment at the beach ($10–15 USD), and snorkel on your own. A guide is not required but the volunteer team at the Centro Ecológico Akumal entrance provides a brief orientation. Guided tours from Playa del Carmen also operate here if you prefer a fully arranged option.
Approximately 20–25 minutes north of Tulum on Highway 307. It is a natural first or last stop on a Tulum day, particularly combined with Cenote Dos Ojos which is 5 km north of Akumal off the same highway.
Yes — the bay is calm, shallow (2–4 meters), and the turtle encounters are appropriate for children who are comfortable in water with a mask and life jacket. The volunteer guides are attentive to groups with children.
