Piton de la Fournaise has erupted more than 200 times since the seventeenth century, which makes it one of the most active volcanoes on Earth and one of the most closely watched. Reunion Island is barely 2,512 square kilometres.
Within that space the terrain rises from sea level to 3,070 metres at Piton des Neiges, a dormant shield volcano that built the island roughly three million years ago. Erosion did the rest. Three vast amphitheatres — Cirque de Mafate, Cirque de Salazie, Cirque de Cilaos — collapsed inward from its flanks, leaving walls a kilometre high and valleys that road engineers eventually declined to enter.
Mafate has no road at all. Its hamlets, called îlets, are supplied by helicopter and on foot, a rotation flown several times a week from the coastal airfields. That practical service is the ancestor of the modern reunion helicopter tour: aviation here began as logistics, not leisure. Freight and medical evacuation flights mapped the cols and updrafts long before any passenger paid for a window seat. Corail Hélicoptères operates from Aéroport de Pierrefonds in Saint-Pierre, on the island's dry southern coast, where morning air is typically stable and visibility across the highlands is at its best.
UNESCO inscribed the Pitons, cirques and remparts of Réunion on the World Heritage list in 2010, covering roughly forty percent of the island's surface within the Parc National de La Réunion. The citation names the subalpine tamarin forests, the endemic ferns, and the sheer remparts themselves. Much of that inscribed territory is visible only from above or after two days of walking. Trou de Fer, a waterfall system dropping some 725 metres through the Bébour forest, is the clearest case; hikers reach a viewpoint above it, while aerial sightseeing flights descend into the gorge itself.
The volcano remains the other magnet. The Enclos Fouqué caldera, breached toward the sea, channels lava down the Grand Brûlé to the Route des Laves, where flows from 2007 and later eruptions have paved over the coastal road in black basalt. Scenic helicopter flights over Reunion Island trace that corridor, then climb back over Dolomieu crater. Volcanic geology, cloud forest and collapsed calderas sit within twenty minutes of each other by air. A well-planned reunion helicopter tour compresses a week of mountain driving into a single flight path, and the island's topography, not the operator, dictates the route.
