This park has so many excellent opportunities to do interesting things and see spectacular sights that it would take a long time to exhaust them all.
We participated in a Golden Monkey tracking which is one of the experiences that are unique to this area as these monkeys live no where else in the world. They were easily accessed after a brief hike that was not very strenuous. The terrain is gently rolling, not steep or rugged. We saw a large number individuals and had ample time to observe and photograph.
It is not difficult to get good photos, but a longer lens is recommended as they can be more active and move away from you if you get close.
There is very large and aggressive stinging nettle in the area, so wear thick pants and be cautious when touching the plants around you. I do not react very much so had no difficulty with it but some people can react quite badly.
If I am able to return to the area I will definitely go back!
