Not far from La Digue, the rich depths of Coco Island are a real natural aquarium. Around this idyllic isle bathed by crystal-clear waters, you can swim amid turtles and hundreds of fish above a wealth of coral. Top-quality sites are not rare in the Seychelles, but lovers of snorkeling should not leave the archipelago without exploring this exceptional spot.

How to get there?

Coco Island lies a few miles from La Digue. Unless you have your own boat or you are visiting the Seychelles in a catamaran, you will need to book a half-day tour from a local operator to visit the spot. Excursions to Coco leaving from La Digue generally include a stop on Félicité Island. Since the spot is part of the Coco Island Marine Park, there is an entrance fee (included in the price of your tour) and the area is regulated.

Exploration

The area to explore is at the edge of Coco Island (facing the small white sandy beach) and near the islands surrounding it. During an organized excursion, there is little scope for independence and you will generally be accompanied by your guide throughout the exploration. He can show you the most interesting areas and give you a good glimpse of underwater life.

Near the small islands, you will alternatively cross clear areas interspersed with spectacular granite rocks and impressive coral beds (↕12-24ft/4-8m). Near the beach, it is less deep (↕3-10ft/1-3m) and the coral is rarer, but there are just as many fish.

The underwater life in this spot is impressive in density and variety. Shoals of powder blue tangs, hawksbill sea turtles, spotted eagle rays, parrotfish, blue damselfish, and deep red anthias… The coral (mainly of the acropora type) is very well preserved.

Sea turtle watching in La Digue Island

snorkeling-hawksbill

Hawksbill sea turtles are a familiar sight in La Digue and its neighboring islands, like Coco Island. 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 at a distance (6 to 10ft) from sea turtles
  3. Do not chase a turtle swimming away
  4. Avoid sudden movement and allow sea turtles plenty of space when they come up to the surface to breathe

On La Digue main island, Anse Patates and Anse Caiman (both with free shore access) are also excellent snorkeling spots to encounter hawksbill sea turtles.

These spots are accessible to anyone with basic snorkeling skills, and feeling comfortable in the water and with his snorkeling gear. You will enter the water from the shore (beach, pontoon, ladder, rocks) or from a boat. The water height in the sea entrance area is reasonable, but you will not necessarily be within your depth. Moderate currents can occur in the area, even when the sea conditions are good. The distance to swim to reach the most interesting snorkeling areas of the spot does not exceed 200 meters.

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.
