Read up on here and you will find all sorts of activities. And just so you know, it is YS Falls not Y's Falls. YS is beautiful and as recommended you can combine it with Pelican Bar for a great day. I recommend leaving around 8am at the latest so that you can beat the crowd to YS as well as not feel rushed going to Pelican Bar. Once you get to Pelican you might want to chill for a couple of hours. Our last trip we saw the most amazing sunset in our boat coming from Pelican headed back to Black River(where you set off from land). HAVE FUN!
