Why Réunion National Park stands out
Réunion National Park is best known for its dramatic volcanic landscape featuring the three spectacular cirques of Mafate, Salazie, and Cilaos, massive caldera-like depressions surrounded by towering remparts. The park protects Piton de la Fournaise, one of the world's most active and accessible volcanoes, which draws over 400,000 visitors annually. The island's exceptional endemism distinguishes this park, with species like the Réunion cuckooshrike, Réunion Island day gecko, and numerous endemic palms and other flora found only here. The contrast between the stark lunar landscapes of the volcanic highlands and the lush tropical forests in the lower elevations creates a unique ecological mosaic.
Réunion National Park history and protected-area timeline
The establishment of Réunion National Park traces back to 1985 when proposals for protecting the island's mountainous interior first emerged. The Réunion Environmental Charter and Regional Development Plan formalized the principle of creating a park in Les Hauts during the mid-1990s. Between 2000 and 2003, an intensive consultation process involved the French state, regional authorities, and local municipalities. Following a positive public survey in 2004 where all 24 communes approved the project, the French Prime Minister signed a decree in March 2003 acknowledging the park project. After years of negotiations on boundaries and objectives, the park officially came into existence on March 5, 2007, through a decree approved by the Council of State. The Administration Council took office in April 2007, and the park's charter was developed between 2007 and 2009. On August 1, 2010, UNESCO inscribed the "Pitons, cirques and remparts of Réunion Island" on the World Heritage List, recognizing the site's outstanding universal value. The park's creation replaced two earlier nature reserves—the Mare-Longue Nature Reserve established in 1981 and the Roche Écrite Nature Reserve created in the 1990s.
Réunion National Park landscape and geographic character
The landscape of Réunion National Park is defined by its volcanic origins and dramatic topography. The island rises from the Indian Ocean as a massive shield volcano, with two primary volcanic massifs forming its backbone. Piton des Neiges, an extinct volcano that has not erupted for approximately 12,000 years, dominates the island's center and reaches 3,071 meters—the highest point in the Indian Ocean. Despite its name, permanent snow is rare at the summit due to the island's tropical latitude. Piton de la Fournaise remains actively erupting and is among the world's most monitored volcanoes. The park's most spectacular features are the three cirques—Mafate, Salazie, and Cilaos—massive amphitheater-like depressions formed by volcanic collapse and subsequent erosion. These cirques feature towering cliff walls called remparts, with the Bras Rouge River cutting through Cilaos creating narrow gorges. The landscape also includes the Plaine des Sables, a lunar-like volcanic plain, and the Enclos, the active volcano's unique caldera. The western slopes feature remnants of semi-evergreen forest, while the eastern slopes receive year-round rainfall supporting different vegetation patterns.
Réunion National Park ecosystems, habitats, and plant life
The nature of Réunion National Park is characterized by extraordinary endemism resulting from the island's isolation and diverse microclimates. Of the 850 known native plant species on Réunion, 230 are endemic, with half of those endangered. The park encompasses 110 different habitat types spanning from coastal zones to the alpine summit, including tropical rainforests, semi-evergreen forests, tamarinaies (Acacia heterophylla woodlands), pandanaies, and volcanic rock fields. The forests of Réunion are classified as the Mascarene forests ecoregion, considered endangered by the World Wildlife Fund. The park is part of the Madagascar and Indian Ocean Islands biodiversity hotspot, recognized by Conservation International as a global priority for conservation. The rough topography has facilitated allopatric speciation, with bird species like Barau's petrel, Réunion harrier, Réunion cuckooshrike, and Réunion grey white-eye evolving distinct populations. The park's core area contains 94% of the island's biodiversity, representing more than four-fifths of the Mascarene Islands' total biodiversity.
Réunion National Park wildlife and species highlights
The wildlife of Réunion National Park reflects the island's position as a biodiversity hotspot with high levels of endemism. Among the most notable endemic birds are Barau's petrel, which nests on the island's high peaks, the Réunion harrier, the Réunion cuckooshrike, and the Réunion grey white-eye—together representing half of the island's 18 bird species. The park supports endemic reptiles including the Réunion Island day gecko and the Endormi (a legless skink). Notable butterfly species include Papilio phorbanta and Salamis augustina. The Mauritian flying fox, a large fruit bat, has recolonized the island after being locally extinct. However, introduced species including cats, rats, and giant land snails pose significant threats to native wildlife. Approximately 25% of the island retains original vegetation, with most native habitats now restricted to higher elevations within the park. The loss of at least 22 bird species since human colonization highlights the conservation challenges facing this island ecosystem.
Réunion National Park conservation status and protection priorities
Réunion National Park represents one of the most important conservation areas in the Indian Ocean region due to the island's exceptional endemism and the threats facing its native ecosystems. The park protects 94% of Réunion's biodiversity within its core area, making it critical for the survival of numerous endemic species. The UNESCO World Heritage designation in 2010 provides international recognition and additional protection mechanisms. However, the park faces significant challenges including competition from approximately 830 naturalized exotic plant species, of which 50 are considered invasive. Habitat loss to agriculture and development, combined with predation by introduced species, has driven the extinction of numerous native species. The park's charter commits to reversing biodiversity loss, and management includes partnerships with local communes across all 24 municipalities. Conservation efforts also focus on protecting the remaining old-growth forest areas, particularly at Mare Longue and La Grande Chaloupe, which contain some of the best-preserved examples of low-altitude tropical forest.
Réunion National Park cultural meaning and human context
Réunion National Park encompasses inhabited areas within Les Hauts, the traditional highland region of the island. Small settlements called îlets are scattered throughout the cirques, where communities practice agriculture and maintain traditional的生活方式. These communities have faced tensions with park management, with inhabitants criticizing restrictions on farming activities that they consider part of their historical tradition. The park's charter explicitly includes objectives to preserve and add value to the culture of the highlands and ensure the transmission of its values. The cultural landscape reflects centuries of human settlement in these mountainous areas, with evidence of agricultural terraces, traditional housing, and pastoral practices. The park also encompasses areas of historical significance related to the island's colonial past and the development of highland communities. The designation as a national park, rather than a strict wilderness preserve, acknowledges the long history of human presence in these lands.

Best time to visit Réunion National Park
Réunion National Park can be visited year-round, though the austral winter months from June to September offer generally more stable weather conditions in the highlands. The warm and humid summer season from December to March corresponds with the cyclone season and can bring heavy rainfall, particularly on the eastern slopes, though this period also sees the volcano at its most active. The transition months of April, May, October, and November often provide good conditions for hiking with fewer crowds. Temperature decreases significantly with elevation, so visitors to the high peaks should prepare for cool conditions regardless of the season. The Piton de la Fournaise area is popular year-round, though visibility and access can change rapidly depending on weather. The cirques experience their own microclimates, with Salazie often receiving more rainfall than Cilaos due to its eastern exposure.
