Wilhelmina MountainsAbout Wilhelmina Mountains
The Wilhelmina Mountains are a remote mountain range in central Suriname’s Sipaliwini District, forming part of the Guiana Shield. The range is covered by tropical rainforest and includes the country’s highest named peaks.
The range’s terrain consists of ridges and isolated plateaus that give rise to rivers and waterfalls; it supports high biodiversity and remains sparsely populated and largely undeveloped. The highest point in the range is Julianatop, at about 1,280 metres.
Exploration and mapping were carried out by colonial-era and later scientific expeditions, but the area has remained little altered by large-scale development. Access is logistically challenging and typically undertaken for scientific, conservation or specialised eco-tourism purposes.
Geographically the Wilhelmina Mountains lie in the interior of Suriname within Sipaliwini District, forming part of the country’s central highlands and the broader Guiana Shield region.
- Environment: The range is largely covered by intact tropical rainforest and forms headwaters for several interior rivers, making it important for biodiversity and hydrology.
