Chissioua Dzaha is a small, uninhabited island located south of Mohéli, forming part of the Mohéli Marine Park. The island is characterized by its rugged volcanic rocky coasts and sparse but specialized vegetation. Geologically, it is a remnant of earlier volcanic activity in the archipelago and provides valuable insights into the erosion of island formations. The waters surrounding Chissioua Dzaha are known for their exceptional marine biodiversity, including intact coral reefs and numerous fish species. For endangered sea turtles, the island serves as an important resting area, although there are few sandy beaches suitable for nesting. The steep cliffs also provide nesting sites for various seabirds that hunt in the nutrient-rich waters. Historically, the island remained largely unaffected by human settlement due to its inaccessibility. Today, it is a destination for ecologically oriented boat tours showcasing the raw beauty of the Comorian island world. Its protected status as part of the national park ensures the preservation of this fragile ecosystem from overfishing and pollution. The geological structure of basalt and tuff makes it an interesting object of study for geoscientists.

📋 Practical info

🧭

Getting there

This rocky offshore elevation can only be approached via a chartered boat trip from the coastal villages. Direct landings are often impossible, so most visitors observe the formation from the deck.

📅

Best season

The calmest ocean conditions occur between late spring and early autumn, facilitating a smooth boat ride. Rough seas during the winter months prevent small vessels from safely navigating around the rocks.

⛰️

Terrain & paths

The relief is characterized by steep, jagged volcanic cliffs rising abruptly from the sea. The sheer vertical faces serve as an important and undisturbed sanctuary for various seabird colonies.

🎒

What to bring

Binoculars and a camera with a telephoto lens are highly recommended for observing the seabirds from a distance. A waterproof bag for electronics is essential to protect gear from ocean spray.

🅿️

Parking

Land transport is parked on the mainland at the small harbors or beaches where the boat tours begin. It is generally safe to leave cars near the homes of the local tour operators.

⚠️

Safety

Attempting to climb the treacherous, slippery rocks is highly dangerous and generally strictly forbidden. Visitors must trust the boat captain's judgment regarding safe distances from the crashing waves.

⏱️

Time needed

A boat tour circling the rocky elevation typically lasts about one to two hours. Often, this is combined with other coastal sightseeing activities to create a half-day marine itinerary.
