Beds, food and transport in Nairobi are cheap by any standard; the single line that decides your budget is whether you go into a national park, because the park fee costs more than several days of everything else.
The park fee is the whole budget
Kenya Wildlife Service revised its conservation fees on 1 October 2025. Nairobi National Park is now USD 80 for non-residents, KSh 1,350 for Kenyan residents and KSh 1,000 for East African citizens. The Nairobi package covering the park, the Animal Orphanage and the Safari Walk is USD 105, KSh 1,750 and KSh 1,300 respectively. Budget it as a one-off, not a daily cost.
Matatus, and when to stop using them
The 14-seater and 33-seater matatus cover the whole city for small change, but they have no fixed stops, no timetable and they are not the thing to be figuring out after dark with a bag. Learn one or two routes by day, and use Bolt or Little at night — an app ride across town still costs a fraction of a hotel transfer.
Where the cheap beds are
Two clusters: Milimani Road and the streets around it, walkable to the city centre and the museum, and the Lang'ata and Karen side, where the campsites and eco-camps sit within reach of the park gates. Camping with your own tent is the cheapest option in the city and is genuinely common.
Free green space instead of paid attractions
The Nairobi Arboretum, off State House Road, is a walkable forest of labelled trees and monkeys minutes from Westlands and the city centre, with a small gate fee and no safari pricing attached. It is the obvious cheap morning when you have already spent your money on the park.
What a day costs
A dorm bed or a campsite pitch runs roughly KSh 1,500 to 2,500, a plate of ugali with sukuma wiki or beans from a local kitchen KSh 200 to 400, nyama choma at Kenyatta Market from about KSh 800 a shared kilo, a matatu hop KSh 50 to 100 and a cross-town Bolt KSh 400 to 900. Add USD 80 on the day you enter the park.
