Hiking in Reunion Island is one of the strongest active travel experiences in the Indian Ocean. The island combines cirques, forests, waterfalls, ridges, lava flows and volcano trails in a compact but demanding terrain.
The best hiking route is not the longest one. It is the route that matches weather, fitness, access rules and the time you have on the island.
Piton de la Fournaise
The Piton de la Fournaise hike is the classic Reunion Island volcano experience. Most visitors approach through Bourg Murat, Plaine des Sables and Pas de Bellecombe before entering Enclos Fouqué when access is open.
The trail can include Formica Leo, volcanic rock, old lava flows and views toward Dolomieu crater. The landscape can feel lunar, but the route remains a mountain route. Check closures, gas, wind and heat before leaving the parking lot.
Piton de la Fournaise is an active volcano, and it is often described as one of the more accessible active volcanoes in the world. That does not make it harmless. Weather, eruption alerts and official closures should decide the day.
Piton des Neiges
Piton des Neiges is the highest point of Reunion Island. It is older than Piton de la Fournaise and helps explain how the island formed over millions of years. Reaching the summit requires stamina, layers and a realistic start time.
Mafate
Mafate is the great walking world of Reunion Island. No road enters the cirque. Villages, ridges and guesthouses are linked by trails, so hikers should plan stages honestly and book ahead.
Cilaos and Salazie
Cilaos gives hikers thermal history, mountain roads and routes for different levels. Salazie and Hell-Bourg are greener, wetter and more atmospheric. Rain can make trails slippery, so backup plans matter.
Lava tunnels and guided routes
Lava tunnels can be explored with specialist guides in suitable areas. These trips need helmets, local expertise and respect for safety rules. They are not a substitute for the volcano hike, but they add context to the island geology.
Reunion Island is a French overseas department, so many visitors expect familiar infrastructure. The trails can still feel remote. Mobile coverage, rescue access and road conditions vary, especially when weather changes fast.
How to plan
May to October is often the most comfortable hiking period. Mountains can still be cloudy, so start early. A seven-day hiking trip should choose two or three priorities. A ten-day trip allows Mafate, the volcano and one cirque with more room.
Beginners can choose viewpoints, coastal paths and short botanical walks. Experienced hikers can add longer stages, but short distances can still become demanding because of altitude, heat and rough ground.
Suggested first hiking route
A first active trip can start with a short west coast walk, then build toward Piton de la Fournaise when the weather is clear. Keep the volcano day flexible. If clouds or closures arrive, use that day for a market, a viewpoint or a lower trail.
The second major experience can be Cilaos or Salazie. Cilaos works well for dry mountain drama and a strong road journey. Salazie is greener and often wetter, with waterfalls, Creole houses and Hell-Bourg as a useful cultural pause.
Mafate deserves more respect than a quick tick on a list. Choose a realistic entry point, book a gite early and remember that walking times depend on heat, rain, mud and elevation gain.
What to book ahead
Book mountain accommodation, difficult guided hikes and lava tunnel trips before arrival in high season. Guides are especially useful when the route involves uncertain weather, volcanic terrain or travellers who are not used to steep island trails.
Also check transport to trailheads. A beautiful route can become stressful if the start is far from your base or if the return plan depends on a narrow bus or shuttle window.
For the volcano, check the latest access note before paying for a long transfer. For Mafate, confirm both the gite and the walking stage. For Cilaos or Salazie, keep one easier day after a hard climb.
Safety and responsible hiking
Stay on trails, respect private areas and mountain accommodation, and do not underestimate local warnings. Carry water, food, sun protection, rain layers and offline maps.
Reunion Island hiking works best when travellers slow down enough to notice geology, Creole villages, forests and weather instead of treating every trail as a fitness test.
