This guide covers the best things to do in Ol Donyo Sabuk, how to get there, what you will pay, when to go and what to carry. Whether you want a tough Saturday workout, a quiet picnic or a camping weekend, the things to do in Ol Donyo Sabuk are easy to plan once you know the basics.

How to get to Ol Donyo Sabuk from Nairobi
The park is a comfortable day trip, so reaching the things to do in Ol Donyo Sabuk is easy. Most visitors drive from Nairobi through Thika and reach the gate in about an hour and a half, depending on traffic. KWS gives these directions:
- Drive from Nairobi to Thika town, roughly 85 km by the route KWS describes.
- Continue about 22 km along the Garissa Road to Makutano junction.
- At Makutano, follow the KWS signs and turn right.
- Drive about 4 km on an all-weather murram road to Donyo town.
- At Donyo, turn right and drive a further 2 km to the main gate.
If you do not have a car, take a bus or matatu from Nairobi to Thika, then another matatu towards Donyo town, which is roughly 2 km from the gate. Our Nairobi to Meru bus fare and schedule guide shows how the Thika Road corridor works, and you can browse more bus booking guides here to plan the Nairobi leg. Public transport on the last stretch can be slow, so start early.
Prefer not to organise anything? Several operators run guided day trips, often combined with Fourteen Falls. Check what is included before you pay, especially ranger fees, park entry and transport.
The best things to do in Ol Donyo Sabuk
Now to the main event. These are the things to do in Ol Donyo Sabuk that visitors enjoy most.
1. Hike to the summit
The summit hike is the headline among all the things to do in Ol Donyo Sabuk. KWS puts the route at about 9 km from the main gate to the top, and most people take around three hours to climb. A full round trip often takes four to five hours.
The trail is a wide murram track that climbs steadily through dense montane forest, then opens into woodland, scrub and an exposed summit area. Some shortcuts cut straight up the slope. They are steeper and rougher, so only take them if you are fit and your ranger agrees.
Most people describe the hike as moderate. It is not technical, but it is long, and the heat on the lower sections can catch you off guard. Start early, carry plenty of water and wear shoes with good grip. At the top you get a wide view over farmland, rivers and hills, and on a clear day you can see far-off highlands, including Mount Kenya.
2. Visit the McMillan grave
History lovers will enjoy this one. Sir William Northrup McMillan was an American-born settler and philanthropist who made his home on the mountain in the early 20th century. His grave, and that of his wife Lucie, lie near the summit, and KWS lists the burial site among the park’s main attractions. Guides also point out a nearby grave said to belong to Louise, who joined the McMillan household as a young girl. Ask your ranger for the story.
3. Watch for wildlife
Wildlife spotting is one of the most exciting things to do in Ol Donyo Sabuk, though you need realistic expectations. Buffalo are the dominant large animals, which is exactly why KWS wants hikers to go with an armed ranger. Others reported in the park include bushbuck, leopard, olive baboon, colobus monkey, vervet monkey, dik-dik, duiker, bush pig, rock hyrax, porcupine, python and monitor lizard.
Do not expect a Maasai Mara-style game drive. The forest is thick, many animals are shy and sightings are never guaranteed. Baboons and monkeys are the easiest to see. KWS rules say you should keep at least 20 metres away from wildlife and never feed animals.
4. Go birdwatching
Among the quieter things to do in Ol Donyo Sabuk, birdwatching is a real pleasure. The park is reported to have around 45 bird species, including the augur buzzard, African hawk eagle and purple-breasted sunbird. Early morning is best, when the forest is cool and the birds are active. Bring binoculars, which KWS specifically recommends.
5. Enjoy a picnic
If a 9 km uphill hike is not your plan, a picnic is one of the easiest things to do in Ol Donyo Sabuk. KWS lists picnicking as a main activity, and the grounds near the gate work well for families and small groups. National parks in Kenya are plastic-free, so pack food in reusable containers and carry all your rubbish out.
6. Camp under the stars
Camping is one of the more adventurous things to do in Ol Donyo Sabuk. KWS lists the Turacco public campsite and the Summit Lookout special campsite. Special campsites need advance booking through the park warden or KWS reservations. The park does not offer self-catering accommodation, so bring your own tent, sleeping bag, cooking equipment, food and drinking water. Never leave campfires unattended, and confirm facilities and fees with KWS first.
7. Take photographs and soak up the views
Photography is one of the easiest things to do in Ol Donyo Sabuk, even if you only walk part of the trail. Forest, open ridgelines and wide plains make for good photography, especially in the early morning and late afternoon. Stay on the trail and never step off the path for a better angle.
8. Add Fourteen Falls to your day
Fourteen Falls is not inside the park, but it is a short drive away on the Athi River, and many visitors add it to the things to do in Ol Donyo Sabuk. Treat it as a relaxed second stop after a long climb, with its own entry arrangements and fees. If you enjoy planning trips like this, our things to do in Diani Beach with family guide shows how we put together a full-day plan, and you will find more ideas in our Kenya travel section.

Safety tips for things to do in Ol Donyo Sabuk
A few habits make the visit safer and more enjoyable:
- Hike with your ranger and stay with the group.
- Keep at least 20 metres from wildlife, and never feed animals.
- Stay on established trails and roads, and keep to the 40 km/h speed limit.
