Hole #2 is great for spinning and edge work, but still not deep enough to loop I don't think. Hole 3 is the same, but mellower. Hole #4 is an all day surf machine. Notice I didn't mention the hole #1 at the top... good for eddy turn practice! The slalom gates are always in too and that can be workout in itself.
Ya most of the biking is really only available east of the river around BV and Salida, and there is plenty of that to keep you busy for several days. But the Colorado Trail was about 50% clear two weeks ago, there may be some good rideable stretches depending on how quick that last storm melted, especially from BV south to Hwy 50.
