I recently hiked Kilimanjaro (via Machame route 6 days) with Chacha tours and it was AMAZING! I was a solo traveler, and was a bit nervous about traveling by myself, but Chacha made me feel completely comfortable and at ease about everything. Chacha is one of the most energetic and happy people you will ever meet and will make sure you have a great experience. Everyone on his team is very professional and will give you all the support you need to get you to the summit! I was very pleased with my overall experience and highly recommend Chacha!
