This is a fairly easy trail through the rainforest to the big tree camp (Mti mkubwa in Swahili). More really an introductory trail. It says it takes 4 hours, but we comfortably did it in 2:15 hours. Nice are the colobus monkeys along the way and the forest is beautiful. Due to the elevation you won’t be bothered by mosquitoes anymore and as such it’s a relaxing experience. The camp itself gets pretty crowded as it’s small and the bathroom facilities are horrendous - just be aware.
