The bus lets you off at the top of the Falls where you canrent a locker. Cost is $8 and you get $3 back when you return the key. You also need some pretty good water shoes.
You will wait in one of the lines for the guide to take youto the bottom of the falls, which starts on the sandy beach. The guide will take you slowly up the rocks. I did enjoy this climb and recommend you at least do it once in your lifetime. If you can’t make it all the way up, there is several escape routes which will allow you to leave the falls. The water was very warm and the never came over the knees so this is perfect for kids.
