Hell's Gate National Park is famous for its natural hot geysers, eagle and vulture breeding grounds. Driving, walking, camping, cycling and rock climbing can be enjoyed within the park. Bird and animal life abound in Hell's Gate National Park and birds of prey are of special interest especially the lammergeyer. Zebras, baboons and gazelles are common sights and occasionally cheetahs, leopards and ostrich are encountered. Hell's Gate is one of the few game reserves where visitors can explore by foot and walk amongst the elands, zebras and hartebeest. Fischer's Tower, formerly a volcano's plug, is a column of volcanic rock named for a German explorer who explored the Hell's Gate area in 1882. The Central Tower and Njorowa Gorges are popular spots for viewing the surrounding scenery. Natural steam vents rise from fissures in the volcanic rock and obsidian, a black glassy rock formed from cooled molten lava, is a common feature of the landscape in Hell's Gate. Olkaria Geothermal Station, the first of its kind in Africa, is located within Hell's Gate National Park. Olkaria generates power from underground with super-heated pressurized water and is expected to eventually supply half of Kenya's energy requirements. . In the park, close to the Central Tower ranger station, is the Oloor Karia Masai Cultural Center. The center features singing, dancing and jewelry making demonstrations by local Maasai people.
