Aquarium North is a shallow, sheltered reef dive site located off the northern coast of Mauritius, not far from the popular resort town of Grand Baie. True to its nickname, the site resembles a living aquarium — teeming with colourful reef fish, vibrant hard and soft corals, and an astonishing variety of marine creatures at virtually every turn. The site is accessible by boat from Grand Baie and is frequently visited by both dive operators and snorkelling excursion boats, making it one of the most popular underwater destinations in the region.
The reef sits at a comfortable depth range, typically between 5 and 15 metres, making it ideal for beginners, open water students, and snorkellers while still offering enough variety to keep experienced divers engaged. The sandy seabed between coral formations provides excellent visibility, often reaching 20–30 metres on calm days. The protected lagoon environment means conditions are generally mild, and the site can be dived year-round.
Aquarium North earns its name with an extraordinary cast of reef inhabitants. Divers can expect to encounter:
The reef itself is a patchwork of staghorn and brain corals, sea fans, and sponges, providing habitat for a huge diversity of species. Cleaner stations are active throughout the reef, where small wrasse and shrimp service larger fish — a mesmerising behaviour to observe.
Aquarium North benefits from its sheltered position within the northern lagoon of Mauritius. The site is generally calm, with minimal current — ideal for newer divers and those who prefer a relaxed, exploratory pace underwater. Visibility is typically excellent, ranging from 15 to 30 metres depending on season and weather. Water temperatures hover between 24°C in the cooler austral winter months (June–September) and 28–29°C during summer (November–March), meaning a 3mm wetsuit is comfortable year-round, though some divers opt for a shorty or skin suit in summer.
The depth range of roughly 5–15 metres means dive times can be extended comfortably, with bottom times of 45–60 minutes common for recreational divers. The site's shallow nature also makes it excellent for multiple dives in a day.
Aquarium North can be dived throughout the year, but conditions are generally at their finest between April and November, when winds are lighter and visibility is at its peak. The dry season (May to October) brings the clearest water and most stable conditions. During the wet season (December to March), brief periods of reduced visibility may occur after heavy rain or swell, but the site remains diveable on most days. Summer months also bring warmer water temperatures, which can increase marine activity and make the dive even more vibrant.
