Just a short hop from Djibouti City, right in the Gulf of Tadjoura, the Musha and Maskali islands are the perfect sea escape: two little coral islands surrounded by turquoise lagoons, reefs full of life and white-sand beaches with hardly anyone on them. Half an hour by boat separates the hot, bustling capital from a world of crystal-clear water, ideal for spending the day swimming, snorkelling or diving.
Musha (or Moucha), the larger one, holds Djibouti's biggest mangrove, a key ecosystem for fish, birds and turtles, and has a small eco-lodge for anyone who wants to stay the night. Maskali, smaller and wilder, is a magnet for divers thanks to its well-preserved reefs. Together they form a protected marine reserve and are candidates for UNESCO World Heritage status, a sign of the value of their corals and mangroves.
This guide explains how to visit the islands from the capital, when to go, what you'll see underwater and how to do it while looking after a fragile environment. For many travellers, a day on Musha and Maskali — with whale shark season just around the corner — is the best sea memory of their whole trip to Djibouti.
Musha and Maskali are geologically young coral islands, formed by reefs growing over the shallow floor of the Gulf of Tadjoura, in a region shaped by the tectonics of the Afar rift. For centuries they were a refuge for Afar fishermen and a stopping point on the gulf's routes; in French colonial times, Musha was even used as a lazaretto and quarantine station for ships entering the port. Today they are a protected marine reserve and one of the country's great natural attractions, whose natural history is told on our history page.

Origins, formation and what the sources say.
Geologically speaking, the Musha and Maskali islands are very young. They are coral islands, built up over thousands of years from coral skeletons and limestone sediment piling up on the shallow floor of the Gulf of Tadjoura. Unlike the volcanic mountains that surround the gulf, these low, flat islands were made by living things: tiny coral polyps that, generation after generation, built the reefs that surround them today.
The Gulf of Tadjoura, where they sit, is a remarkable place in the Earth's history. It lies at the western end of the Gulf of Aden, right where the great rift separating the African plate from the Arabian plate cuts into the continent. It is, quite literally, an ocean in the making: the seabed here is slowly pulling apart. That tectonic activity explains the gulf's deep waters and steep mountains, and also the warm, salty conditions in which corals thrive.
On that seabed, in warm, nutrient-rich waters where the Red Sea meets the Gulf of Aden, coral reefs and seagrass meadows grew up, along with mangroves in the sheltered parts of Musha. The result is a highly biodiverse ecosystem, with reef fish, turtles, rays and seabirds, that makes these little islands a small natural treasure right on the capital's doorstep.
For centuries, long before Djibouti City existed, the waters of the Gulf of Tadjoura belonged to Afar fishermen and sailors, and to the trade routes linking the coastal ports with Arabia and the Ethiopian interior. With no fresh water and fully exposed to the sun, Musha and Maskali never had a permanent population, but fishermen knew them well. They fished the lagoons and fish-rich reefs and used the beaches as shelter.
The gulf belonged to an ancient maritime world, part of the Red Sea and Indian Ocean trade, with sailing dhows going back and forth between the two shores of the Bab el-Mandeb strait. In that world the islands served as landmarks for navigation and fishing rather than places to live.
That bond with the sea is still alive today. Small-scale fishing is still part of life on the gulf, and the health of the Musha and Maskali reefs matters not just for tourism but also for the communities that live off the sea. In a way, the islands link that long fishing tradition with the new interest in protecting and showcasing the country's marine life.
When France arrived and founded Djibouti City in the late 19th century, the islands near the port took on a new role. In colonial times, Musha Island (Moucha) was used as a lazaretto: a quarantine station where ships, cargo and people suspected of carrying contagious diseases were kept in isolation. This was standard practice in the big ports of the steamship era, when epidemics such as plague and cholera travelled by sea.
Being close to the port and surrounded by water made it ideal for the job: cut off from the mainland, yet within sight of the capital. Over time, once the age of the great lazarettos had passed, the island lost that role and, like Maskali, became practically uninhabited, left to the sun, the wind and the sea.
That past left few visible traces, but it is part of the history of a gulf that has always been tied to shipping. The islands went from fishing spots to a colonial health station and finally, in independent Djibouti, to a protected natural area and tourist destination: three very different lives for two little coral islands.
After Djibouti's independence in 1977, and especially in recent decades, people began to see the natural value of Musha and Maskali in a new light. The coral reefs, the seagrass meadows and the Musha mangrove, the largest in the country, were recognised as fragile and valuable ecosystems, both for their biodiversity and for their role in fishing and coastal protection. The islands and their waters came to be treated as a marine reserve.
The Musha mangrove in particular is a key ecosystem: it acts as a nursery for fish and crustaceans, a refuge for birds and a natural barrier against erosion. The reefs, which sit where the rich waters of the Red Sea and the Gulf of Aden meet, are home to a varied population of reef fish, turtles and rays. Protecting all of this became an environmental priority for a country that sees its natural heritage as a tourism resource for the future.
That recognition led to the Moucha and Maskali islands being added to UNESCO's tentative list, meaning they are among the sites Djibouti puts forward as candidates for World Heritage status for their natural value. The bid sums up the change in outlook: from forgotten quarantine islands to biodiversity gems worth protecting.
Today, Musha and Maskali are among Djibouti's top natural attractions and the capital's go-to escape to the sea. Half an hour by boat from the hot, busy streets of Djibouti City, they offer turquoise lagoons, reefs teeming with life, mangroves and almost untouched beaches. The small eco-lodge on Musha lets you spend the day or stay the night, and the capital's dive centres have made the islands their playground.
Their future depends largely on tourism growing without harming what makes it possible. Corals are under threat worldwide from warming seas and pollution, and these reefs are no exception. That's why visitors are urged to tread carefully: don't touch the corals, don't leave any rubbish, and go with responsible operators. The World Heritage bid is also a commitment to conservation.
For travellers, Musha and Maskali are Djibouti's friendly, sunny side. A country known for its extreme deserts and salt lakes shows its other half here, the marine one, with crystal-clear water and surprisingly rich wildlife. A small, fragile treasure right on the capital's doorstep, and a good example of the country's bet on nature tourism.
