Very many years ago, about a century, in fact, white settlers and other travelers going upcountry from Nairobi stopped at this place near Thika town for a drink and sometimes to spend the night. Located at the site of two waterfalls, Chania and Thika, it was a beautiful place to pass a few hours.
Nowadays, there is really not much reason to come to Thika or stay here. You'd be better off staying in Nairobi, though you wouldn't get the peaceful grounds and waterfalls there.
The grounds used to be covered with hibiscus and bougainvillea, and brightly colored weaver birds were all over the place. You can still find some of the flora, but the birds are more scarce now. The grounds are still well maintained, and in the evenings and weekends, many locals come to have a drink on the open ground outside the dining room. Some thatched umbrellas have been erected at the Chania falls viewpoint, but they are never occupied, since there is no bar nearby, and no seats. Dinner was terrible, but breakfast wasn't too bad.
A small animal sanctuary has been established, costing about $3 to enter. Not worth it - you'll see an ostrich and some other small creatures. An onsite souvenir workshop should present you with some good bargains of carvings and other curios.
The rooms are pretty rustic, but they have the essentials - a bed and a clean, working bathroom. Mosquitoes could be a problem, but the hotel can provide mosquito nets. Ask for the rooms facing the open grounds towards the falls. You won't see the falls, but you'll get a nice breeze. Air-conditioning is not available.
