Hell's Gate history in brief

Hell's Gate was once the outlet of a prehistoric freshwater lake. That old outflow is the background to the gorge and the cliffs you see today. The park takes its name from the gorge.

The protected area is much younger. Legal Notice 13 of 2 February 1984 created Hell's Gate National Park, with an area of 68.25 km². The land is managed by the Kenya Wildlife Service (KWS). Today the park is known for cycling, cliffs and its geothermal power stations. If you want to see the landscape yourself, compare Hell's Gate day trips from Nairobi.

The tentative list is a first step, not a World Heritage inscription. For most visitors, the 2012 and 2019 floods are the dates that matter in practice, because they explain why the gorge is treated with care. Read the section below before you plan any walk.

Rocks, towers and the old lake outlet

What the landscape tells you about the past.

Fischer's Tower

Fischer's Tower is a rock column 25 m high, made of material that rose into a crack and hardened. It stands near the main gate and is named after Gustav Fischer. See the Fischer's Tower guide.

Central Tower and the caves

Central Tower and the Obsidian Caves are geological features of the park. Do not assume that you can enter the caves. Ask KWS before you plan a visit.

Joint management with Longonot

The 2010 to 2015 management plan covered Hell's Gate and Mount Longonot together. For the volcano on the other side of the lake, see Mount Longonot.

Steam and pipes

The power stations separate steam from water. The steam goes to the power plant, and the separated water is pumped back underground. The pipes along the roads belong to this system. They are not an invitation to enter operating areas.

Vulture cliffs

The cliffs are important nesting sites for Rüppell's vultures, which is part of why the park matters for conservation. The wildlife guide covers the animals.

Hell's Gate tragedy: the flash floods of 2012 and 2019

The facts, stated plainly.

On the evening of Sunday, 22 April 2012, a flash flood came through the gorge. At first, one death and six missing people were counted. The next day the toll stood at seven. On 1 September 2019, a second flash flood killed seven people, among them members of a tourist group.

After the 2019 flood the gorge was closed to visitors. The gorge was reopened later, but access still changes. Confirm the current status with KWS before you plan a descent into the narrow lower gorge.

Both floods show one point. Rain outside the park can send dangerous amounts of water through the gorge, even when the sky above you is dry. Read the Hell's Gate weather guide and the gorge guide for what that means for your visit.

Power stations, a film story and the park today

The park also lies beside geothermal power stations, called Olkaria I to V. KenGen runs several of them, but not all. Olkaria III belongs to a separate private operator. Conservation groups have raised concerns about light, noise and vibration from development in the area. You can read about the plants and the spa in the Olkaria guide.

Hell's Gate is also often said to have inspired the setting of The Lion King. Film makers are said to have visited in 1991 to study the landscape and the animals. The director has said that Pride Rock was invented in Burbank, so no rock in the park is the real one. The Lion King page sets the story out.
