Grassholm

Grassholm is a rocky outcrop off the coast of South Georgia, rising steeply from the ocean with dark volcanic stone as its primary structure. The formation provides nesting habitat for large seabird populations that make use of the cliff faces and crevices.

The rock formation developed through volcanic activity millions of years ago as part of South Georgia's geological history. It represents a component of an older rock complex that formed in the harsh Southern Atlantic environment.

Scientists regularly conduct research expeditions to study the rock formations and document the numerous bird species that inhabit this remote location.

This rock outcrop is only reachable by specialized expedition vessels, making visits extremely limited and weather-dependent. Visitors should prepare for rough seas, strong winds, and challenging landing conditions.

The rock formation hosts one of the region's densest penguin colonies, with thousands of birds nesting there each year. This concentration of wildlife makes it a focal point for ornithologists and nature researchers.
