Mount Longonot

Mount Longonot rises 2,776 meters above sea level, featuring a massive caldera measuring 8 by 12 kilometers with a forest-covered crater floor.

The volcano experienced its most recent eruption during the 1860s, forming its current structure through substantial trachytic lava flows approximately 21,000 years ago.

The mountain received its name from the Maasai word Oloonong'ot, referring to the multiple steep ridges that characterize its slopes.

A 3.1-kilometer trail leads from the park entrance to the crater rim, while the complete rim circuit extends 13.5 kilometers and requires 4-5 hours.

Steam vents along the crater walls indicate ongoing geothermal activity beneath the surface, with recorded geodetic measurements confirming active magmatic systems.
