Mount Longonot, an extinct volcano, lies just East of the lake and Hell's Gate National Park lies Southeast of the lake. The area of the park is 68.25 km2. And is 14 km after the turnoff from the old Nairobi-Naivasha highway. This Park was named for its pair of massive red tinged cliffs framing a geothermal active interior of steam vents and bubbling springs. The park is home to a profusion of plains game and birdlife. Walking is permitted, making it ideal for hiking, biking, and rock climbing. Boat trips on the lake are widely available, and are a great way to spend an afternoon or morning. Sunsets are always stunning, with the haunting call of a Fish Eagle high over the Lake bringing the day to a perfect end.
Hell's Gate National Park is particularly impressive with soaring red cliffs, isolated volcanic plugs, spreading grasslands dotted with game and a deep gorge where visitors can walk. Fischer's Tower is a challenging rock climb. This park is excellent for succulents, birds of prey and other bird species. It is characterized by diverse topography and geological scenery. It is also the home of the rarest of Kenya's vulture population, the Lammergeyer. The climate is warm and dry and the vegetation is mainly grasslands and shrub lands with the latter being dominated by Leleshwa and several species of acacia. The gorge and cliffs are breeding sites for several species of raptors and swifts. 103 species of birds have been recorded in the park.
There is a geothermal project at the far end of the park.
Main road access to Naivasha is directly from Nairobi. The main highway continues from Naivasha to Nakuru. Naivasha is just over an hour from Nairobi. There is an airstrip in Naivasha, with charter flights available. Some lodges and guesthouses here have private airstrips as well.
