I have visited the falls many times. Yes, it can be a bit slippery to get down there, but part of the small path has things to hold on to.
During the dry season, it should be fine. I have been during the wet season and we got to see three waterfalls, the main one and two others.
I had never seen so much water and the whole beach area was covered with water as well. Absolutely beautiful, but a little tricky getting down there.
If you are capable, it is worth the trip, definitely!!
The path is very short, a bit steep, but I have seen many elder people there as well, so doable.
