La Gran Sabana
Bolívar
The Gran Sabana is an extensive natural region located in southeastern Venezuela, forming part of the Guianan savanna ecoregion and extending into the Guiana Highlands. Covering approximately 10,820 square kilometers, it lies within Bolívar State near the borders with Brazil and Guyana. This area is renowned for its striking landscape featuring isolated table-top mesas known as tepuis, deep valleys, rivers, waterfalls, and dense jungles. The region is part of Canaima National Park, Venezuela's second-largest national park and a UNESCO World Heritage Site since 1994. The Gran Sabana is ecologically significant, hosting a rich diversity of flora and fauna, including many endemic species unique to the area. Its geology is dominated by ancient Precambrian sandstone formations, especially the resistant Mataui Formation that shapes the tepui cliffs. The climate is generally mild, with average temperatures around 20°C, cooling at night and at higher elevations. The largest settlement in the region is Santa Elena de Uairén, a city founded in 1923 linked historically to diamond mining. The Gran Sabana remains a destination for ecotourism and scientific research due to its natural beauty and biological importance.

Histoire
The Gran Sabana region has been historically significant since the colonial era, when it was part of the legendary quest for El Dorado, attracting explorers seeking gold and precious stones.
In 1962, the Venezuelan government declared Canaima National Park to protect its unique ecosystems, initially excluding the Gran Sabana.
However, in 1975, the park was expanded to include the Gran Sabana's rolling plains and ecologically important areas.
This expansion helped preserve the region's natural heritage and promoted ecotourism.
The park's designation as a UNESCO World Heritage Site in 1994 further highlighted its global environmental importance.
