Brazil Cachoeira do Prumirim, Ubatuba

Powerful cascade plunging over layers of flat rock in a forest area popular for swimming & climbing.

Bring a tripod and play with the shutter speed to get abstract shots of the water fall or the grand scene.
If you continue hiking along the path there are lots of opportunities for Macro photography as well.

I'd recommend bringing at least one wide angle lens for the grand scene and a super zoom to capture abstracts from the waterfall itself.

Easy hike, the easiest is to reach to the nearby restaurant and walk down the hiking path, but the location is also accessible by public transport.
