I was at Niagara Glen last Sunday. It was still as nice as ever. The store at the top sells a map of all the trails in the Niagara Parks - spend $3 and you help the parks as well as making sure you choose the right trails in the Glen. I suggest going along to the right at the bottom of the stairs, heading for the "water" trail first so you can see the rapids close up. You can buy tickets for the rapids boat ride at the store if you are inspired by what you see.
