7. See the beginnings of man at the Olorgesailie Prehistoric Site
About an hour outside Nairobi in the Great Rift Valley, Olorgesailie is where you can actually stand in the same place early humans once lived.
It’s a key archaeological site, with tools and fossils dating back around 1.2 million years. You’ll come across hand axes and cleavers made by Homo erectus, along with fossilized bones from animals like ancient baboons and hippos.
The museum on site gives helpful background, and newer discoveries show early humans using pigment and possibly trading across long distances. The landscape itself is worth a look too—layers of exposed earth show how the environment has changed over time.
If you take a guided tour, it's usually led by someone who knows the excavation history well and can walk you through the latest findings.
8. Meeting Rothschild Giraffes at Langata Giraffe Centre
Roughly 30 minutes from downtown Nairobi, the Giraffe Centre focuses on helping the endangered Rothschild’s giraffe. Thanks to its breeding program, giraffes from here now live in protected areas like Lake Nakuru and Soysambu, and visiting here is by far one of the best things to do in Nairobi.
When you visit, you can feed them pellets from a raised platform—their 20-inch (50 cm) tongues are part of the experience. Kids especially tend to love it.
There’s also a short walking trail through a patch of nearby forest and sometimes conservation talks or short films in the auditorium. It’s a good place to stop, especially if you’re traveling to Kenya with kids.
