Willy,
Wells Gray is the land of waterfalls. I believe there are over a dozen that are worthy of seeing. Spahats Falls is the first major falls you come to on the Park road. For a first time viewer, it is very impressive. But when you you see Helmcken for the first time, you are blown away. These pictures were taken several years ago. During the winter months, if it is cold, the snow cone at the bottom can get really impressive. This year, there is barely anything for a cone. I can't tell you what the best season to see them is. All four seasons are equally awesome. The Spring, during runoff, has an incredible amount of water and force. The summer, the greenery is out and the fall is in bright colors. On cold winters, the snow cone is unreal.
