There are stairs that people can go up instead of actually climbing the falls. The stairs run right alongside the falls. Alot of people used them.
The falls were a lot more difficult to climb then I thought they would be. It was really a lot of fun, but you really had to CLIMB. I'd imagine some people would have some difficulty. The guides are great though. I'm sure they'd help.
it is a physical climb, the rocks can be slippery. There is a stairway that goes alongside the falls, lots of folks do this, there are also "outways" along the fall if you find the climb to challenging.
Don't climb the waterfalls, there was a lady in her 60s in front of us and she felt pretty bad. Use the walkway and if you want to take a pictures in the waterfalls you can enter them at some of the parts just for that.
I fell too and cut and bruised my leg. The lovely staff was no help to anyone, they make everyone hold hands and help each other but they do nothing and expect tips. My boyfriend was helping an out of shape over weight woman and let go of me cause it took two hands to help her, that is when I hurt my self. It is a difficult climb for someone who is overweight or not in good shape. It caused a fight between us and we later ditched the woman and her husband and then others were forced to help them. Take the stairs or take a raft down the Martha Brae River instead.
It is dificult and I would recommend using the stairs if at all in doubt. A lady from our ship broke her leg. Felt really bad for her. It was fun we are in our late 40's and our 2 daughters in their 20's did it. We kayaked from our ship to the falls and that was a big mistake. It was hard work out in the ocean and then we had to climb after that!! What an adventure. The girls loved it!!
