St. Brandon, also known as the Cargados Carajos Shoals, is a remote chain of coral reefs, sandbanks and small islets in the western Indian Ocean administered by Mauritius. The archipelago comprises numerous small islets and reefs that form an exposed atoll-like group important for fisheries and wildlife.

The shoals are valued for offshore fishing, seasonal habitation by fishing crews, and colonies of seabirds and marine life including nesting turtles. There are few permanent settlements; human presence is mostly seasonal and associated with fishing and small-scale operations.

Historically visited by sailors and used as a fishing base, the islands have never supported large permanent populations due to their low elevation and exposure. Management focuses on sustainable fisheries and protection of seabird and marine habitats.

Geographically the shoals lie in the open Indian Ocean to the northeast of Mauritius and are physically separate from the main islands, consisting of low sandy islets, reef flats and channels.

  • Visiting access: Access is restricted and typically arranged through licensed fishing operators or with official permission from Mauritian authorities.
  • Wildlife sensitivity: Important breeding site for seabirds and turtles; visitors should follow strict biosecurity and wildlife-disturbance rules.

How to Get to St. Brandon #

St. Brandon (Cargados Carajos) is a remote atoll group belonging to Mauritius with no airport or scheduled public services. It is reached only by boat from the main island of Mauritius - charters or private vessels depart the main island (ports such as Port Louis or ports on the east coast) and the journey takes many hours; there is no public road access on the atoll. Visitors must arrange transport in advance and expect sea transfers and landing by small boat.

Tips for Visiting St. Brandon #

  • St. Brandon is a remote, officially regulated atoll - there are no regular tourist services. Plan a trip through a licensed Mauritian operator and secure any required permits well in advance; most visits are aboard live‑aboard or charter boats from Mauritius.
  • Sea conditions dictate itinerary: the calmer season for offshore travel is the austral winter (roughly May-October), when crossings are generally safer and fishing/boat access more reliable.
