Hell's Gate National Park
Flora and fauna
Dry (September). Depends on season.
Bring your own drinks. It get's pretty hot and you cannot buy any drinks inside the park.
Sleep outside the park at Lake Naivashu.
Possible outside the park at Lake Naivashu.
You are free to roam around and are mostly by yourself. This implies a certain responsibility for your own safety. Don't get lost. If you have a 4x4 or a moto cross bike some "roads" can be pretty fun.
Don't get lost. The park is not overcrowded and signs are scarce and maps can be misleading.
