To tell you the truth only one has gone down and I think it just climbed down the moss or the vine. It is really not that high. I do think I am going to put a plant of some kind in the corner by the rocks or make the rocks higher to make it easier for them as I haven't seen them in the water since that first one so don't know if they will use it . They can get in the water in front of the rock though that is the waterfall that goes down the front but I want them in the water below as well.
