Underwater Wonderland: Diving and Snorkeling the Seychelles’ Best Reefs

The Seychelles, a paradise archipelago scattered across the Indian Ocean, offers more than just postcard-perfect beaches. Beneath the turquoise waves lies a vibrant underwater world, teeming with marine life and boasting some of the best diving and snorkeling spots on the planet. Grab your mask and fins; we’re diving into the Seychelles’ most spectacular reefs!

Diving Deep into Diversity: A Seychelles Underwater Overview

The Seychelles’ unique geological history, as a fragment of Gondwana that drifted away millions of years ago, has shaped its underwater landscapes. Unlike most volcanic islands, the inner Seychelles islands are granitic, providing a diverse range of underwater terrain from shallow coral gardens to dramatic drop-offs and intriguing granite formations. This translates to a rich biodiversity, with over 900 species of fish, 50 types of coral, and an array of other fascinating creatures. Water temperatures are consistently warm, ranging from 26°C to 30°C (79°F to 86°F), making for comfortable diving and snorkeling year-round. Visibility is generally excellent, often exceeding 30 meters (100 feet), especially during the calmer periods between the southeast trade winds (May to September) and the northwest monsoon (November to March).

Praslin: A Snorkeler’s and Diver’s Dream

Praslin, the second largest island, is a fantastic base for exploring some exceptional dive and snorkel sites. Here are a few standouts:

Cocos Island

Cocos Island, a tiny islet just off the coast of Praslin, is a paradise for both snorkelers and divers. The shallow waters surrounding the island are bursting with life. You can expect to see schools of colorful reef fish, like butterflyfish, angelfish, and parrotfish, darting among the coral. With a bit of luck, you might spot sea turtles gracefully gliding through the water or even a harmless reef shark lurking in the distance. The vibrant coral formations here are particularly impressive, showcasing a kaleidoscope of colors and shapes. Several tour operators in Praslin offer excursions to Cocos Island, typically including snorkeling equipment, lunch, and drinks. Prices generally range from €70 to €120 per person, depending on the duration of the trip and the inclusions. For divers, Cocos Island offers deeper sites with opportunities to encounter larger pelagic species like manta rays and whale sharks (seasonal). Dives are usually multi-level, taking advantage of the varied topography.

Getting There: Several tour operators offer boat trips from Praslin (Anse Volbert/Côte d’Or or Grand Anse). The trip typically takes around 30-45 minutes.

Insider Scoop: The current can be strong around Cocos Island, so listen carefully to your guide’s instructions and stay within designated areas, especially when snorkeling.

Sister Islands (Îles Soeurs)

Often paired with a trip to Coco Island, Sister Islands offers a different but equally rewarding experience. Here, you’ll find excellent snorkeling along the shallows bordering the islands, with pristine coral and diverse fish life. The diving is particularly renowned for the chance to see nurse sharks resting on the seabed and the possibility of encountering eagle rays. Keep an eye out for the adorable clownfish nestled within their anemones. The diving is quite shallow, making it suitable for beginners. You may need to pay a park fee to visit the islands as they are part of a protected marine area. This usually includes snorkeling equipment.

How to Get There: Boat trips are readily available from Praslin, often as part of a combo tour with Cocos Island. Again, expect to pay around €70-€120 depending on what is included.

Pro Tip: Pack plenty of sunscreen and a rash guard, as the sun can be intense, especially when you’re spending a lot of time in the water.

Ave Maria Rock

Located near Praslin, Ave Maria Rock is especially suitable for snorkeling due to its shallow, calm waters and abundant fish population. Expect visibility to be very good, averaging around 20 meters. The area is teeming with colorful reef fish, and you also have a very good chance to see green sea turtles. The current is usually gentle, making it a safe and enjoyable spot for beginner snorkelers. Several diving and snorkeling excursions include a visit to Ave Maria Rock. The average cost per person for a half-day trip is approximately €65.

Directional Aid: Ave Maria Rock is easily accessible by boat from Côte d’Or or Grand Anse in Praslin. The journey takes approximately 15 minutes.

Recommendation: Many operators offer lunch included; take advantage of this, as there are no facilities on the rock itself!

Mahé: The Capital’s Underwater Treasures

Mahé, the largest island and home to the capital Victoria, offers a diverse range of dive sites, from easy shallow reefs to more challenging wrecks and drift dives. Here’s a look at some of the best:

Ennerdale Wreck

The Ennerdale Wreck is located about 8km west of Mahé within the marine park and is probably the most famous of the Seychelles wrecks. This 155-meter British tanker sunk in 1970. Now covered in coral and inhabited by diverse marine life, it is a highlight for intermediate to experienced divers. You can expect to see moray eels, stingrays, and large schools of fish. Penetration into the wreck is possible for experienced divers with proper training. Divers require a permit to dive here, usually obtained by booking the tour through a dive center. A two-dive trip to Ennerdale Wreck and another nearby site typically costs around €150-€200, including equipment rental and boat transportation.

Finding the Spot: The wreck lies about 8 km west of Mahé. Most dive operators depart from Beau Vallon or Victoria.

Important Note: Due to its depth (18-30 meters), this dive is generally recommended for certified divers with advanced open water certification or equivalent.

Brissare Rocks

Brissare Rocks, located off the north coast of Mahé, is a group of granite boulders offering diverse underwater landscapes, including swim-throughs and overhangs. The site is great for both diving and snorkeling, with depths ranging from 5 to 20 meters. You’ll find an impressive array of marine life, from colorful reef fish and sea turtles to occasional sightings of white-tip reef sharks. Snorkelers can stay in the shallow areas around the rocks, while divers can explore the deeper sections and search for hidden critters. Expect to pay roughly €60-€100 for a snorkeling trip and €120-€150 for a two-dive trip, depending on the operator and inclusions.

Directional Tip: Access Brissare Rocks by boat from Beau Vallon or nearby beaches on Mahé’s north coast.

Pro Tip: Keep an eye out for nudibranchs (sea slugs) – these colorful creatures are a favorite among underwater photographers!

Shark Bank

Don’t let the name scare you! Shark Bank, located a short boat ride from Beau Vallon, is a fantastic dive site known for its abundance of marine life, including (yes) sharks – mostly harmless white-tip reef sharks, which are often seen resting on the sandy bottom. Other highlights include schools of barracuda, rays, and various reef fish. Visibility is generally good, and the currents are mild, making it a suitable dive for intermediate divers. Expect a two-dive trip to cost around €120-€150, including equipment rental and boat transportation. You can also find snorkeling trips to Shark Bank, where you’ll likely see the same shark species from the surface in shallow areas.

Getting There: Several dive operators depart from Beau Vallon for Shark Bank. The boat ride is relatively short, usually around 15-20 minutes.

Safety First: Always follow your dive guide’s instructions and maintain a safe distance from the marine life.

La Digue: A Small Island with Big Underwater Wonders

La Digue, the smallest of the three main inhabited islands, is famous for its stunning beaches and laid-back atmosphere. It also offers some excellent snorkeling and diving opportunities, easily accessible by boat from the island. You can rent a bike and ride through the island to access boats at certain access points.

Marianne Island

Marianne Island, a small, uninhabited island near La Digue, is a legendary dive site known for its dramatic granite formations and strong currents. This is a dive for experienced adventurers. The currents attract large pelagics like manta rays, sharks (including grey reef sharks and, occasionally, hammerheads), and barracuda. The topography is spectacular, with huge boulders creating swim-throughs and caverns. Diving here requires careful planning and strong swimming skills. Due to the experienced level, anticipate costs to be higher—a two-dive outing could be upwards of €180 with all amenities included.

Approach Advice: Access is exclusively by boat, generally departing from La Digue. Boat journeys can be impacted by weather therefore always book via reliable sources and check conditions beforehand.

Expert Assistance: This particular site is best experienced with a local expert that knows the tides and conditions.

West Point

Located on the west coast of La Digue, West Point is a beautiful snorkeling and diving spot that’s less challenging than Marianne Island. The coral reefs are in excellent condition, boasting a variety of hard and soft corals, and attracting a diverse range of fish. Snorkelers can enjoy the shallow areas close to the shore, while divers can explore the deeper sections of the reef. Look out for turtles, rays, and the occasional reef shark. Boat trips to West Point are easily arranged from La Digue. Snorkeling tours are similarly priced to other spots, costing approximately €60-€100 with lunch, while dive trips typically cost around €100-€150. If you are staying on another island, you can use the available ferry services to visit La Digue.

Getting There: You can reach West Point by boat from various points on La Digue including Anse Severe. You may also be able to negotiate a private day tour.

Local Guidance: Inquire at local accommodations for trustworthy tour operations to avoid rogue operators.
