Mount Longonot

Mount Longonot is the cone every traveller sees on the drive from Nairobi to Naivasha, and the hike to its crater rim is the most popular day climb in Kenya. It is short, brutally steep, entirely unshaded, and it ends on the lip of a forested crater with the whole Rift Valley laid out below. It is also a park in its own right, with a gate, a fee and rules.

What Mount Longonot National Park Is

The Kenya Wildlife Service gazetted Mount Longonot as a national park in 1983 to protect its volcanic landscape, and records the park at approximately 52 square kilometres. The mountain is a relatively young stratovolcano, and the Kenya Wildlife Service states that it last erupted in 1863.

The name comes from the Maasai Oloonong’ot, which the Kenya Wildlife Service translates as mountain of many spurs and ridges, or mountain of steep ridges. That is an accurate description of the mountain and a fair warning about the walk. The flanks are cut into sharp V-shaped valleys by erosion, and the trail up follows one of the ridges between them.

The summit is commonly published at about 2,776 metres. The crater itself is the point of the place: a deep, steep-sided bowl holding a dense forest that cannot be reached from the rim by any sanctioned route, so hikers look down into a closed ecosystem rather than walking through one.

Hiking Mount Longonot to the Crater Rim

The walk divides into two distinct halves. The first is the ascent from the gate to the crater rim, roughly three kilometres of continuous climbing on loose volcanic soil and gravel, typically an hour to two hours depending on fitness. It is steep from the start, it does not relent, and the surface slides underfoot on the way down more than it does on the way up.

The second is the crater rim circuit, a loop of around seven kilometres around the lip of the crater. This is where the mountain earns its reputation. The rim is not level: it rises and falls steeply between high points, the path narrows in places with the crater dropping away on one side and the mountain on the other, and the highest point on the circuit is a substantial climb in itself. Walking the ascent plus the full circuit and returning to the gate comes to roughly thirteen or fourteen kilometres and takes most people four to five hours with stops.

Plenty of visitors climb to the rim, look in, and go back down. That is a perfectly good half-day and it takes about half the time. The full circuit is the better experience and it is a genuinely demanding one.

There is no water and no shade anywhere on this mountain. Everything a hiker needs has to be carried from the gate, and the single most common mistake made here is underestimating how much water a fully exposed climb at this altitude requires.

Hiking in Kenya covers what altitude does to a visiting walker, which matters here because the trailhead is already high and the climb is fast.

What to Expect on the Mountain

The views are the reward and they arrive in stages. From the rim the crater opens below, a bowl of green forest with steam vents visible in places on the inner walls. Beyond the rim, the panorama takes in Lake Naivasha to the north, the floor of the valley in both directions, the escarpments on either side, and on a clear morning the volcanic country around Hell’s Gate.

Wildlife is thin and that is part of why walking is permitted. Buffalo are present on the lower slopes and are the animal the Kenya Wildlife Service warns about. Zebra, giraffe, Thomson’s gazelle and baboon occur on the flats around the base, and raptors work the updrafts along the rim.

Conditions on the rim differ from conditions at the gate. Wind is constant and often strong, the exposure is complete, and cloud can close in quickly enough to remove the view altogether. Carrying a light windproof layer is sensible even on a hot day.

The Kenya Wildlife Service lists camping inside the park, and a night at the public campsite turns the climb into an easy dawn start rather than a drive-and-walk. Camping safaris in Kenya covers how Kenya Wildlife Service campsites work.

Getting to Mount Longonot and Which Route to Take

The Kenya Wildlife Service gives the access as 90 kilometres from Nairobi on the Nairobi to Nakuru highway. In practice most visitors turn off at Longonot town on the old road near Mai Mahiu, from where a short unpaved road of a few kilometres reaches the park gate. Matatus serve Longonot town from Nairobi and Naivasha, and boda bodas cover the last stretch to the gate, which makes this one of the easiest Kenyan national parks to reach without a vehicle.

Naivasha is the natural base, twenty to thirty minutes away, and the mountain combines neatly with Hell’s Gate over two days. It also works as a single long day trip from Nairobi provided the start is early. The valley it stands in is covered on the Great Rift Valley page.

Gates open at 6am and close at 6pm, and visitors must be out between those hours unless camping inside. Starting at opening is not a nicety on this mountain, it is the difference between a pleasant climb and a punishing one, because the ascent faces the sun and there is nothing to hide under after about nine in the morning.

Park Fees, Camping and Cycling at Longonot

Mount Longonot sits in the scenic parks band of the Kenya Wildlife Service conservation fee schedule, alongside Hell’s Gate, Mount Elgon, Ol Donyo Sabuk, Lake Elementaita Wildlife Sanctuary and Kakamega. On the schedule effective from 1 October 2025, published by the Kenya Wildlife Service and checked on 21 September 2026, entry per person per day is KSh 500 for an East African citizen adult and KSh 250 for a child or student, KSh 675 and KSh 350 for a Kenya resident, USD 50 and USD 25 for a non-resident, and USD 20 and USD 10 for an African citizen.

Longonot is also one of the six protected areas where cycling is a priced activity, at KSh 300 or USD 10 per day, and motorcycles are charged at KSh 500 or USD 10. In practice the trail is a walking route and the cycling permission applies to the park roads rather than the climb. Parking at Longonot is charged at KSh 1,000 for East African citizens and USD 30 for non-residents, and does not apply to visitors holding paid park tickets.

The Kenya Wildlife Service lists a public campsite at Oloongonot and special campsites at Nyati and Green. Camping is charged per person per night at the non-premium rate: KSh 250 for an East African citizen adult at a special campsite and KSh 200 at a public campsite, with non-resident adults at USD 35 and USD 20 respectively. Fees are set by regulation and are revised periodically, so confirm the current position before travelling.

Note that fee figures circulating on hiking sites for this mountain are frequently years out of date and quote non-resident entry at a fraction of the current rate.

When to Climb Mount Longonot and What to Carry

The dry months, January to March and July to October, give firm footing and the clearest views. In the rains from mid-March into June and October into December the volcanic soil turns greasy, the descent becomes genuinely slippery, and cloud sits on the rim for much of the day.

The kit list is short and non-negotiable. Two to three litres of water per person, more in hot weather. Shoes with real grip, because the descent is where people fall. A hat, sunglasses and sunscreen, since there is no shade at any point. Something to keep the wind off at the top. Snacks, because the circuit takes longer than most people plan for. Volcanic dust gets into everything, so a buff over the face helps on a windy day.

Rangers are stationed at the gate and guides can be arranged there. The main trail is obvious and does not require one, but a guide is useful for pacing, for the crater circuit, and for anyone hiking alone.
