"As soon asthey see it alongthe Great Rift Valley, hiking enthusiasts want to climbMount Longonot, a dormant volcano thatlast erupted sometime in the 1860s. The name Longonot is derived from a Masai word that means "steep ridges"—fitting because the journey to the top is nearlyvertical, along deep crevices and crumbly rocks. Summiting usually takes about 1.5 hours; from the top,peer into the forest-filled crater and sit under ashaded gazebo to enjoy a picnic. If you have the energy, it’s also possible to hike the rim of the crater, but be warned:Skirting around takes roughly three hours, not including the journey back to the bottom."
