Worth the trip - though seriously you only need a max of 2 days (and one of those can be a fly in/out day).
What was surprising was how hypnotic it was watching the water flow along and then just fall off gracefully. Apparently people throw themselves into the river and just float off to their death on a regular basis.
Lots of photos in the album at www.collins.net.pr/photo
We stayed at the Doubletree which was ok but seriously it's an epicurean wasteland up there so don't go looking for anything worthwhile to eat.
Would highly recommend the boat tour and the walk behind the falls apart from that - don't you think that having this 'water fall'
next to this one
that the irony is lost on most people?
