Snorkeling and Glass-Bottom Boat Tours at Blue Bay Marine Park

Conservation and Marine Biodiversity in the South

Blue Bay Marine Park encompasses 353 hectares of protected lagoon and reef ecosystem situated on the southeast coast of Mauritius. Visitors can observe over 38 species of coral within a five-minute boat ride from the public beach. This area achieved status as a Ramsar site in 2008 due to its significant ecological value and unique underwater topography. While the site was officially declared a marine park in 1997, it remains one of the few places on the island where coral health has remained relatively stable despite rising sea temperatures.

The Coral Reef Ecosystem

The seafloor here sits at an average depth of 5.5 meters, making it accessible for snorkelers of all skill levels. Huge brain corals measuring several meters in diameter dominate the central sections of the park. You will also encounter staghorn corals and fire corals which provide shelter for approximately 72 identified fish species. Look for the distinct blue-striped snapper and the occasional hawksbill turtle near the outer reef edge where the current brings in fresh nutrients.

Water Conditions and Visibility

Water temperatures range from 23 degrees Celsius in August to 28 degrees Celsius in February. Visibility often exceeds 20 meters on days when the southeast trade winds remain calm. Because the park sits in a natural bowl, it remains relatively sheltered compared to the rougher waters found outside the barrier reef. Morning visits are preferable as the afternoon winds often stir up sediment from the sandy bottom and create a surface chop that makes snorkeling less comfortable.

Planning a Visit to the Marine Park

The public beach at Blue Bay serves as the primary entry point for boat excursions and shore-based swimming. Most visitors arrive via the coastal road from Mahebourg which is only five kilometers away. The proximity to Sir Seewoosagur Ramgoolam International Airport means you can often see planes ascending directly over the lagoon every thirty minutes.

Glass-Bottom Boat Excursions

Standard boat trips typically cost between 600 and 1,000 Mauritian Rupees per person depending on the duration and group size. Operators usually provide basic snorkeling gear including fins and masks, though bringing your own equipment ensures a better fit and better hygiene standards. Expect a one-hour trip to include 15 minutes of viewing through the glass floor and 30 to 40 minutes of snorkeling time in the deeper patches. Please note that fees are subject to change—check the official park board or local operators for the most current rates before booking.

Shore Snorkeling and Beach Facilities

You do not necessarily need a boat to see the marine life as the western edge of the beach offers decent snorkeling within 20 meters of the shore. The most vibrant coral patches require heading further out toward the center of the park where the current is stronger and the water is clearer. The public area features basic changing rooms and several food stalls selling local dholl puri and fresh coconut water. Parking is free but the main lot fills up by 10:00 AM on Sundays when local families gather for picnics under the filao trees.

Nearby Attractions and Dining

Pointe d'Esny lies just north of the marine park and offers a much quieter stretch of white sand with fewer boats. If you prefer a more secluded experience, consider booking a day trip to Ile des Deux Cocos which sits within the park boundaries. This private island offers structured tours and lunch packages that contrast with the self-managed feel of the public beach. Mahebourg provides more substantial dining options including waterfront seafood restaurants that are generally less tourist-oriented than those found in the northern part of the island.

Frequently Asked Questions

What is the best time of day to visit the park

Arrive before 9:00 AM to secure a parking spot and enjoy the calmest water conditions. The wind typically picks up after midday which can make snorkeling more strenuous and reduce underwater visibility.

How much do boat tours cost at Blue Bay

Expect to pay around 600 Mauritian Rupees for a shared one-hour glass-bottom boat tour. Private tours or longer excursions to nearby islands will range from 1,500 to 3,000 Rupees.

Can I snorkel directly from the beach

Yes, snorkeling is possible from the shore, but the best coral formations are located further out in the protected zone accessible by boat. Use caution near the boat channels where traffic is heavy throughout the day.

Is there an entrance fee for the marine park

There is no entry fee to access the public beach or the water within the marine park. You only pay for private services such as boat rentals, guided snorkeling tours, or food at local stalls.
