We had a great time with Afrishare who organized our entire week including a hike to the waterfall, a hike to Kilimanjaro and our IB CAS project at Soweto Primary School, in Moshi, Tanzania. The hike to the waterfall was one of the best experiences as well as the coffee tasting session was amazing. I hate coffee usually but I loved this experience! Meeting the local people was great - we really got an insight of Tanzania and the lives of people living there.
However, while working at the primary school we were exposed to many products and carried out intense work. Although it wasn't anyone's fault in particular, 3 students got sick from the paint, used to repaint classrooms at Soweto Primary School, and solvent used by the team hired to help us on construction in the school. Luckily, our teachers and the team then handled it very well, however perhaps there could have been more safety precautions for the chemicals we were exposing ourselves to.
Despite we had this small situation, the entire experience was an experience of a lifetime and one I will never forget. I 100% recommend Afrishare. The safari and entire trip was a great opportunity and one of the best trips I've ever been on.
