The nature and tour by itself are definitely worth it, but the experience depends strongly on which guide you get.
If possible, ask to be with James, who will explain about the Flora and everything, make sure you are fine and be a great guide.
Avoid David if you don't just want to run up and down the mountain and to the waterfalls or hear " we don't use that plant" when you ask about some.
Also, for the big loop to Togo and upper and lower waterfalls, bring water and be sporty.
