Located off the popular resort village of Flic en Flac on Mauritius's west coast, Colorado is a well-loved reef and cave dive site that lives up to its evocative name with a landscape as dramatic and colourful as the American state it references. Sitting at depths ranging from 14 to 25 metres, the site is accessible to intermediate divers and offers enough complexity and variety to keep even experienced underwater explorers engaged. The defining feature of Colorado is its remarkable topography — a series of interconnected passages, swim-throughs, overhangs and cavities that carve through the reef and invite exploration at every turn.
The site forms part of the extensive barrier reef system that lines Mauritius's western coastline, sheltered from prevailing trade winds and offering generally calm, clear conditions. The reef structure here is multi-layered, with shallower coral gardens giving way to deeper drop-offs and rocky formations dotted with cavities. Light filters into the passages in dramatic rays, illuminating the colourful encrusting sponges and soft corals that coat the walls in vivid hues of orange, yellow and purple.
Colorado's diverse habitat supports an impressive variety of marine species. The site is especially known for:
The cave sections of the site host their own micro-ecosystems, with shrimp, small crabs and feather stars thriving in the shelter provided by the rocky formations.
Colorado benefits from the natural shelter provided by Mauritius's west coast, making it a relatively comfortable dive in most conditions. Currents are generally light, which is ideal for exploring the passages and cavities without being swept through them. Visibility is typically excellent, often reaching 20–30 metres, allowing divers to appreciate the full scope of the topography.
Water temperatures on the west coast range from around 24°C in the austral winter months (June to August) to 28–29°C during the summer (December to February). A 3mm wetsuit is suitable for most of the year, with a 5mm option providing extra comfort in the cooler months.
Colorado can be dived year-round, and its sheltered west coast location means it remains accessible even when conditions elsewhere on the island are less favourable. The summer months from November to April bring warmer water and the possibility of encountering larger pelagic species, while the clearer, cooler winter months from May to October often deliver the best visibility. Whichever time of year you visit, Colorado consistently delivers a rewarding dive.
Colorado is easily reached by boat from Flic en Flac, one of Mauritius's most active dive hubs. Numerous PADI-certified dive centres operate from the village, and the site is typically a short 10–15 minute boat ride from the shore. Most operators include Colorado in their regular rotation of west coast dive sites.
