Crater Lake on Mount Bisoke, Rwanda

Discover Rwanda’s Natural Wonder - Crater Lake on Mount Bisoke

Resting inside an extinct volcanic crater atop the towering Mount Bisoke in northwest Rwanda lies a sparkling hidden gem - the mesmerizing Crater Lake. Encircled by the steep inner walls of the natural crater, this rare sight enthralls visitors with its untouched beauty and biodiversity.

A Pristine Alpine Lake

Enclosed within a caldera nearly 600 feet deep, the iconic emerald waters of Crater Lake astound onlookers at first sight. Fed only by rainwater and enclosed by steep eroded walls, it represents a nearly perfectly circular pristine body of water. The distinctive bright green hue reflects the saturated volcanic minerals dissolved in its waters. Surrounding the lake lie picturesque alpine moorlands and grasslands, frequented by endemic wildlife.

Ecological Significance  

This secluded high-altitude rain-filled crater supports unique micro-organisms and algal growth specific to its mineral-rich composition. Diatoms, algae and zooplankton inhabit the lake influencing its vitality and contributing oxygen. The exceptional ecosystem also draws various bird species, including the endangered bearded vulture, inhabiting the taller cliff faces overlooking the crater lake.

Geological Past

Crater Lake lies within the Virunga Massif range of volcanoes, formed due to immense volcanic activity responsible for creating the East African Rift millions of years ago. While the genesis of the lake itself remains partly obscured in history, its cliffs strikingly exhibit various volcanic lava layers accrued through time. Mount Bisoke last erupted over 3700 years ago - since then erosion gradually shaped this natural basin.  

The scenic splendor and scientific relevance of Crater Lake make it undoubtedly one of Rwanda's most treasured geographical landmarks. Though reaching it requires an ascent up Mount Bisoke, gazing into its unique waters is an unmatched and worthwhile reward. This hidden crater jewel remains eternal testament to the awe-inspiring craftsmanship of nature itself!
