Designated as part of a UNESCO World Heritage Site, Piton de la Fournaise offers challenging hiking trails that reward adventurers with breathtaking views of its lunar-like terrain and the Indian Ocean beyond.
3. The Island Was Once Uninhabited
Before European exploration, Réunion Island remained untouched by human presence for thousands of years. Portuguese explorers were the first to document it in 1513, naming it "Santa Apolónia," but they did not settle there. In 1642, the French formally claimed the island and renamed it Bourbon, establishing settlements with enslaved Africans and indentured laborers from India and China to work the sugar plantations. Unlike other Indian Ocean islands with indigenous populations, Réunion’s settlers created a completely new society from scratch. This history of colonization and cultural blending shaped the island’s unique identity, which is still evident in its language, architecture, and cuisine today.
4. A Biodiversity Hotspot
Réunion Island is a biodiversity hotspot, boasting an incredible array of endemic species due to its volcanic origins and isolated location. Nearly 40% of the island is protected as part of Réunion National Park, a UNESCO World Heritage Site. Its dense rainforests, rugged peaks, and coral reefs are home to rare species such as the Réunion cuckoo shrike, the endemic day gecko, and exotic plants like the endemic Réunion fan palm. The diverse ecosystems range from coastal mangroves and dry savannas to cloud forests at higher elevations. Conservation efforts are ongoing to protect the island’s delicate ecosystems from invasive species and human encroachment, ensuring Réunion remains an ecological treasure.
5. The Influence of Indian Culture
Indian culture plays a significant role in shaping Réunion’s identity, dating back to the 19th century when thousands of indentured laborers arrived to work on sugar plantations after slavery was abolished. Today, their legacy is evident in the island’s cuisine, language, and religious practices. Hindu temples are scattered across the island, featuring colorful deities and intricate carvings. Major Indian festivals like Cavadee and Diwali are celebrated with vibrant processions, music, and dance. Réunionese cuisine incorporates Indian spices and techniques, with dishes like cari poulet (chicken curry) and rougail saucisse (spiced sausage stew) being staples in local households. The influence of Indian culture enriches Réunion’s multicultural landscape.
6. Vanilla Production Is a Major Industry
Réunion Island is famous for producing Bourbon vanilla, considered one of the finest varieties in the world. Introduced to the island in the 19th century by Edmond Albius, a former enslaved worker who discovered the hand-pollination technique still used today, vanilla cultivation thrives in the island’s humid tropical climate and rich volcanic soil. The delicate process involves careful hand-pollination of each flower, followed by a lengthy curing process that enhances the vanilla’s signature aroma and flavor. Réunion’s vanilla is highly sought after by chefs and confectioners globally. Vanilla farms, particularly in the eastern part of the island, offer guided tours where visitors can learn about the intricate process from vine to market.
