The 10 Best Places to Swim and Dive with Sea Turtles
Sea turtles are among the cutest animals populating our seas. It doesn’t come as a surprise that both divers and snorkelers are always very happy to spot them and swim with them.
These reptiles (like crocodiles and snakes) have existed for over 150 million years. That’s long enough to have seen the rise and demise of dinosaurs.
As you’ve probably already guessed, sea turtles have adapted their bodies to live in the oceans. In fact, they spend about 96% of their lives at sea.
There are seven species of sea turtle:
- Leatherback Sea Turtle (Dermochelys coriacea)
- Loggerhead Sea Turtle (Caretta caretta)
- Green Sea Turtle (Chelonia mydas)
- Hawksbill Sea Turtle (Eretmochelys imbricata)
- Olive Ridley Sea Turtle (Lepidochelys olivacea)
- Flatback Sea Turtle (Natator depressus)
- Kemp’s Ridley Sea Turtle (Lepidochelys kempii)
Below you’ll find a list of the best places in the world to dive and swim with these amazing creatures.
1. Galapagos Islands, Ecuador
The Galapagos green sea turtle (Chelonia mydas agassisi) is a subspecies of green turtle that can only be found nesting in the archipelago of the Galapagos. This subspecies inhabits the subtropical and tropical waters of the Pacific Ocean, and it can be distinguished from other green sea turtles by its serrated lower jaw and the single pair of scales covering its eyes.
These turtles can be seen while snorkeling and diving in the Galapagos all year long. The principle nesting site is Quinta Playa on Isabela Island.
- Best time: December to March
- Nesting season: December to March
- Hatching season: February to May
2. The Great Barrier Reef, Australia
The Great Barrier Reef is the largest coral reef system in the world. It extends for 1,200 miles (2,000km) and is even visible from space. Although it has been damaged by global warming and pollution, this marine formation is still rich in life, with more than 1,500 species of fish, several different species of whales, dolphins and 6 species of sea turtles.
The nesting sites of the green sea turtle are called rookeries. There are a total of 18 along the Barrier Reef. Five of them, with more or less 30,000 nesting females, are around Raine Island and Moulter Cay in the northern section of the Great Barrier Reef. The other 13 are in the southern part, where around 8,000 females go to lay their eggs in a group of islands called Capricorn Bunker.
- Best time: May to October
- Nesting season: Late October to February
- Hatching season: Late December to April
3. Ari Atoll, Maldives
The Maldives are made up of more than 1,000 coral islands divided into 26 ring-shaped atolls in the Indian Ocean. These atolls are famous for their white coral sand and their incredible marine life.
Diving and snorkeling in the Ari Atoll is unforgettable and appropriate even for beginners. You’ll be delighted by manta rays, schools of tropical fish, nudibranchs, starfish, dolphins and whale sharks.
Sea turtles are everywhere, even in the shallow water. You can easily see hawksbill turtles while they eat sea sponges along the reef (in the foraging area). Sometimes it is possible to swim with olive ridley and green turtles. However, these turtles rarely lay their eggs in the Maldives.
- Best time: January to April
- Nesting season: Very rare
- Hatching season: Very rare
4. Maui Island, Hawaii
Hawaii is a volcanic archipelago in the central Pacific Ocean and is home to 5 of the 7 species of sea turtles. The most commonly seen are the green sea turtle (locally called honu) and the hawksbill (honu’ea). Less frequently seen are the leatherback, the loggerhead and the olive ridley.
Hawaiian green sea turtles are easily spotted year round while snorkeling or diving along the south and west coast of Maui, especially in front of South Maui Turtletown. You can see them feeding on algae, lying on the ocean floor or coming up to the surface to breathe. You might even spot one on the beach basking in the sun.
Keep in mind that you shouldn’t harass these turtles. First of all, harassment will disturb the turtles, but also harassment of turtles is illegal in the Hawaii.
- Best time: April to October
- Nesting season: Green sea turtles in the northwestern Hawaiian Islands nest in the Papahanaumokuakea Marine National Monument from May to October. 90% of Hawksbill nesting activity has been recorded on the Ka’u coastline of Hawaii Island.
- Hatching season: Late June to December (hawksbill turtles)
5. Marsa Alam, Egypt
Marsa Alam is a town in the southeastern part of Egypt and is one of the most famous dive destinations in the Red Sea. If you are looking for a stunning coral reef, tropical fish, dolphins, reef sharks, napoleon fish and especially sea turtles, this is the right destination for you.
Abu Dabbab Bay is widely known as a beautiful sandy beach where it is possible to swim with green sea turtles and dugongs. Both feed on seagrass and are usually seen while snorkeling not too far from the beach. If you are looking for hawksbill sea turtles, you should dive or snorkel along the reefs, where they can be easily spotted while feeding.
Both species rarely lay their eggs along the coast. Most nesting activities occur on offshore islands where access by land is forbidden by law. Sometimes nesting season can start earlier or later than usual, depending on the temperature.
- Best time: June to September
- Nesting season: July to August (green turtles); July to August (hawksbill turtles but in the Hurghada area)
- Hatching season: August to October (green turtles); July to October (hawksbill turtles)
6. Sipadan, Malaysia
This place is ideal for swimming with the green and hawksbill sea turtles that inhabit the reef all year round. You will be surrounded by them (seeing 20 to 30 per dive). They don’t mind divers, simply eating or coming up to the surface to breathe. Moreover, the water is always warm with a temperature of 26-30°C (79-86°F).
- Best time: April to November
- Nesting season: April to September (both species)
- Hatching season: June to November (both species)
7. Cook Island Marine Reserve, Australia
Cook Island Marine Reserve is a small protected area not too far from the Gold Coast in southeast Queensland. This place is a sanctuary for marine life, inhabited by a wide variety of fish including parrotfish, pufferfish, groupers, leopard sharks, wobbegong and resident green sea turtles. The turtles can therefore be spotted all year round.
When you interact with sea turtles, avoid touching them and keep a distance of 15 feet (4-5 meters). In this way, you can enjoy seeing the turtle and avoid disturbing this marine reptile.
Green and loggerhead turtles have both been recorded nesting on beaches in northern NSW with hatchlings emerging from nests from January to May. It’s worth noting, however, that Cook Island doesn’t have large turtle rookeries or the mass hatchings found at various sites in Queensland.
- Best time: May to October
- Nesting season: November to March
- Hatching season: January to May
8. Akumal, Playa del Carmen, Mexico
Akumal Beach is ideal for snorkelers (even for beginners), because the small bay is protected by a reef and is shallow (15 feet / 5 meters in depth). The bed of the sea is sandy and covered by a carpet of plants that attract the turtles.
- Best time: May to August
- Nesting season: May to October (Green turtles only)
- Hatching season: July to December
9. Tortuguero National Park, Costa Rica
If you are looking for two of the most spectacular wildlife events in the world (nesting and hatching of sea turtles), you have to go to Tortuguero National Park on the northeastern coast of Costa Rica. This place is really rich in biodiversity. Here you’ll find mangroves, capuchin monkeys, hundreds of birds and, of course, sea turtles (green, hawksbill and leatherback), which can be spotted year round.
Green and leatherback sea turtles come to the beaches to lay their eggs. During the green turtle’s nesting season more than 2,000 females come to the area. Most of them lay eggs at night. So if you want to observe them, you’ll need a local guide, as it is forbidden to go on the beach after 6:00 pm.
The dry season is from November to April, but along the Caribbean coast you can experience a tropical rain all year round.
- Best time: March to August
- Nesting season: July to October with the peak in August for green and hawksbill turtles; March to July for leatherback turtles
- Hatching season: September to December for green and hawksbill turtles; May to September for leatherback turtles
10. La Flor Wildlife Refuge, Nicaragua
Locally called Refugio De Vida Silvestre La Flor, this Nicaraguan wildlife refuge is one of the best places in the world to see thousands of female sea turtles coming to lay their eggs.
Located on the Pacific Coast of Nicaragua, close to San Juan del Sur and Costa Rica’s border, La Flor Wildlife Refuge hosts more than 100,000 olive ridley sea turtles from July to December. These turtles come to nest alongside the occasional hawksbill, leatherback and green sea turtle.
This phenomenon is locally called “arribada” and offers the opportunity to satisfy your sea turtle obsession!
Keep in mind that the wet season is from May to October, but as a tropical area, the temperature in Nicaragua is always between 23 and 32°C (73 and 90°F).
- Best time: July to November
- Nesting season: July to December
- Hatching season: September to February
How to Approach a Sea Turtle
Sea turtles are animals that tend to be indifferent to our presence. All of us, from beginners to expert divers, are attracted by their presence and we often approach them to admire or take footage of them.
Find out how to interact without disturbing them.
Swimming and Diving with Turtles
Contrary to what you might think, the carapace, plastron and skull of these reptiles is very sensitive. For this reason, sea turtles should never be touched.
Touching can frighten the animals and prolong their apnea, causing severe lung damage in the worst cases. Always remain at a distance from sea turtles and do not hinder their swimming.
During the deposition of eggs, do not point any lights or camera flashes at the female, especially in the phase preceding the deposition itself. Light may cause the turtle to stop laying eggs and leave. If you are lucky enough to observe this behavior, keep a distance and be as quiet as possible.
Should you be the lone spectators of this event, remember to report the nest to the appropriate authorities. This way the turtles eggs can be protected.
When the eggs hatch and the newborns are coming out of the sand, avoid touching them and do not block their path to the sea.
Avoid excessive flash photography when photographing sea turtles. Do not point your flash directly into their eyes.
ID Your Sea Turtle
Identifying sea turtles is very important for researchers in order to monitor the populations.
If you are diving or snorkeling close to a sea turtle, take photographs of both sides of its head and of its full body. The heads of sea turtles is covered by dark scales (facial scutes) that are unique to each individual, just like our fingerprints.
Photographs of the full body are required to find out if is a female or a male. Males have a long tail, females and juveniles have short tails that are often invisible.
Send this material plus the date and location of the sighting to one of the associations listed below. They will identify the animal and send some info about it to you. If it’s a new individual, you might even get to name it!
The natural predators of juvenile sea turtles are numerous. Even while sea turtles are still in their eggs, crabs enjoy digging in with their claws.
Perhaps the most dangerous time in a young turtle’s life is when it must make the dash from nest to sea. During this stage, baby turtles can be eaten by crabs, birds, dogs, foxes and other animals. Once they arrive in the water, fish also become predators. It’s estimated that only 1 in every 1,000 baby sea turtles becomes an adult.
One way to help prevent the death of baby sea turtles is to take caution when visiting nesting beaches with pets. Always have your animals on a leash and keep an eye on what your pet is playing with.
After adulthood is reached, the number of predators decreases dramatically. At this stage, sharks and killer whales are the only other marine animals that are dangerous to sea turtles.
The biggest danger to sea turtles is man (and his activities). Among these activities, we can list:
- Entanglement in fishing gear: Fishing nets can become a deadly trap for these reptiles. Because they can no longer breathe on the surface, they die by drowning.
Fishing hooks can also hurt and kill sea turtles.
- Poaching and illegal trade of eggs, meat and shells: These practices are reducing the number of adults and newborns, hindering the development of new generations.
- Ocean pollution, plastic and marine debris: These pieces of garbage can be ingested by turtles and lead them to death. Moreover, pollution can kill or damage their natural food.
- Coastal development: New construction on the coast can destroy or reduce the natural nesting area, impeding the deposition of the eggs.
- Global warming: This global phenomenon is altering marine ecosystems, crippling a natural balance that has existed for millions of years.
All of these activities are bringing sea turtles closer to extinction.
Sea Turtle Saviors
Fortunately, there are several groups of experts that have founded associations which work to protect sea turtles through research, education, training and habitat protection.
