Lac Karihani

Lac Karihani is a crater lake in the Bandraboua area of northern Grande-Terre, Mayotte, set in a volcanic depression typical of the island's interior. It is reached by a walking trail through surrounding forest, and the setting is greener and quieter than the coastal lagoon scenery that dominates most visitors' trips. The visit starts with a taxi-be from Mamoudzou toward Bandraboua, a ride of around 20 minutes costing about 2 euros, followed by a trailhead roughly one kilometre from the main road. A round trip normally takes two to three hours. The path climbs gently through tropical vegetation, with sections unshaded and exposed to sun, and arrives at the crater rim, from which the lake's surface is visible below, framed by dense vegetation. Birdwatchers can look for local species at dawn, and early morning is also the best time for wildlife sightings and cooler walking. Access is free, and there are no facilities at the lake, so water, a hat and sturdy hiking shoes are essential, along with insect repellent. Trails may be muddy after rain and signage is limited, so hiking with a local guide is helpful for first-time visitors. Crowds are essentially absent, and the lake draws hikers and birdwatchers rather than beachgoers. Photographers can capture the lake from the rim at first light, when mist and soft colour add atmosphere. Swimming is generally not advised, and visitors should respect the site by taking all rubbish away and staying on existing trails to limit erosion.
