Treetops Hotel is a hotel in Aberdare National Park in Kenya near the township of Nyeri, 1,966 m (6,450 ft) above sea level on the Aberdare Range and in sight of Mount Kenya. First opened in 1932 by Eric Sherbrooke Walker, it was literally built into the tops of the trees of Aberdare National Park as a treehouse, offering the guests a close view of the local wildlife in complete safety. The idea was to provide a machan (hunting platform on a tree during shikar in India) experience in relative safety and comfort. From the original modest two-room tree house, it has grown into 50 rooms. The original structure was burned down by African guerrillas during the 1954 Mau Mau Uprising, but the hotel was rebuilt near the same waterhole and has become fashionable for many of the rich and famous. It includes observation lounges and ground-level photographic hides from which guests can observe the local wildlife which comes to the nearby waterholes.

The hotel is known as the location where Princess Elizabeth acceded to the thrones of the United Kingdom and Commonwealth Realms upon the death of her father George VI while she was staying there in 1952.
