How to Get to Kikuletwa Hot Springs
Firstly, you should know that there is no public transport to Kikuletwa Hot Springs, the only ways to get there is either through a private tour or by using a dala dala + taxi/boda boda combination. If you book a visit, you have about four hours to spend during the spring, which is plenty of time for a good period.
Going on your own to Chemka Hot springs is more stressful and time consuming, but much cheaper. From Moshi, you will have to take the dala dala towards Arusha and get off at Boma. The way to Kikuletwa Hot Springs is in bad shape, so prepare for a good half an hour to an hour on a bumpy, unpaved road, full of holes and sometimes flooded.
