Are you looking to explore a single spot with a nice barrier reef that is well preserved, teeming with fish, and with seagrass beds full of green turtles and stingrays? Then head for Akumal, the most famous and busiest spot in the Mayan Riviera. Despite the high visitor numbers and the restricting rules for turtle sightings, it is still worth the trip.  Facing a white sandy beach lined with coconut trees, the crystal-clear waters are the guarantee of a great snorkeling experience.

How to get to the Akumal snorkeling spot

The small village of Akumal is in the heart of Riviera Maya, about 22 miles/35km south of Playa del Carmen and 15 miles/25km north of Tulum. You can easily reach the area with group taxis (known locally as vans or “collectivos”), regular bus lines, or taxi. If you’re coming by car, you should be aware that it can be hard to find free parking.

It is no longer allowed to snorkel with the turtles unless you have a guide in Akumal. To see the turtles, you’ll have to sign up for a tour. Tours are carried out in groups that have a max. of 6 people plus an authorized guide. The tours follow one of the two snorkel trails set in the bay (see map below, areas 1 and 2).

Life jackets are mandatory, to prevent snorkelers from skin diving and disturbing sea turtles. Swimming and sighting of sea turtles are only allowed from 9 am to 5 pm. Snorkeling freely on the barrier reef (zone 3 on the map) seems, at this point, to be still permitted.

Akumal snorkeling tips and recommendations

This spot can be divided into two distinct areas: the seagrass beds near the beach, visited by green sea turtles and southern stingrays, and the barrier reef, divided at one point by a pass, some 270-330 yards offshore.

Green sea turtles in Akumal
Green sea turtles are easy to encounter in Akumal Bay’s shallow seagrass meadows.

The seagrass beds (↕3-7ft/1-2m) begin near the swimming area and extend for several dozen meters. The green sea turtles and the stingrays that visit the area are the spot’s main attractions. It shouldn’t take too long for you to come across them, and it is almost a guarantee that you will see them.

Don’t disturb the turtles, which come to the spot to feed and rest, and don’t forget that stingrays have a sting that can cause serious lesions. You have to respect a minimum 10ft/3m distance away from the turtles when in the water. This area can only be snorkeled following the underwater trails with a guide.

If you want to snorkel the barrier reef (zone 3 on the map), you’ll have to swim at right angles to the beach towards the barrier reef. Do not cross the marked turtles sighting areas (see map).

After crossing sandy areas, you will soon see the reef (↕3-20ft/1-6m). It is covered with sea fans and several species of hard coral, including Porites, branching Acropora, and leafy coral. Snorkeling along the reef, you will come across shoals of grunts, blue tang, parrotfish, or butterflyfish.

The area around the pass, shown by buoys, is much deeper (↕20-26ft/6-8m) and the reef drop-off is spectacular. Spotted eagle rays and yellow stingrays sometimes visit this area.

Coral reef and grunt in Akumal
Sea turtles are not the only underwater attraction in Akumal: the coral reef, covered with sea fans, is also worth exploring.

Stay away from the pass, as boats use it to access the beach. The current is strong in the area, so don’t try to go to the outer reef.

Restaurants & accommodation in Akumal

In Akumal (near the beach and on the main street) there are several small supermarkets, snack bars and restaurants. A few hotels have opened on the beach, particularly the Akumal Bay Beach and Wellness Resort, the Hotel Akumal Caribe and Las Villas Akumal.

Sea turtle watching in Akumal Bay


Sea turtles are a very familiar sight in Akumal Bay. In order to be a responsible snorkeler, be sure to respect the following rules when observing them:

  1. Do not attempt to touch or ride sea turtles
  2. Stay a distance (6 to 10ft) from sea turtles
  3. Do not chase a turtle that is swimming away
  4. Avoid sudden movements and allow sea turtles plenty of space when they come up to the surface to breathe

These snorkeling spots are accessible to beginners and kids. You will enter the water gradually from a beach, or in a less than 3ft. deep area. The sea is generally calm, shallow, with almost no waves or currents. These spots are usually located in marked and/or monitored swimming areas. It is not necessary to swim long distances to discover the sea life.

This level only apply when the spot experiences optimal sea and/or weather conditions. It is not applicable if the sea and/or weather conditions deteriorate, in particular in the presence of rough sea, rain, strong wind, unusual current, large tides, waves and/or swell.
