First, make sure you don't mind getting your shoes dirty. If it rains, the trail will become very muddy and slippery. To be honest, the starting point is more thrilling than the waterfall. You can't swim in the river because the water is slowly getting infected with leptospirosis - there are warning signs everywhere telling visitors this. It's a relatively easy hike - not very steep, but the mud makes it very slippery and there are no railings. There are lots of people of different ages (from babies to the elderly) who come here for hiking, and many choose to use crutches (highly recommended). There is also a cafe and bathroom facilities in front of the parking lot.
