The hike up to the Mt Longonot crater rim takes about half a day, though going up the 3.2 kilometers to the rim of the crater can take anything from 45 minutes to 2 hours, depending on your speed and stamina. You also need a walking stick, as the hike can be quite stiff for the first 3 kilometers or so. Climb Mt. Longonot and see Lake Navaisha on a private hiking and wildlife tour from Nairobi into the magnificent Great Rift Valley. Enjoying the personal service and flexibility of a private guide, you can set your own pace as you climb the volcano, walk around the crater rim, and then explore Lake Navaisha, with the option to book a wildlife cruise on the Rift Valley’s highest lake.
