Pick your way through the tight trees in the upper part of the drainage, and then you'll see it open up. If there is enough snow, there are pillow options aplenty straight down the gut. Venture left or right and the drops get bigger, up to about 20 feet if you're feeling good.
At the bottom of the gully, don't miss the skin track that cuts left underneath the east-facing parts of the Terrain Park. Follow this all the way back to the Dream Lake trail (Don't drop in thinking it'll take you back to your car, it won't).[more]
Mountains just west of Boulder. Tons of great Alpine climbing and great ski descents. Generally there is good snow late into the spring, but doesn't really get good until mid-winter.
How to Get There
Go West out of boulder, through Nederland, and continue on. The approaches are a little longer in the spring, because of slightly lower elevations, but they average a couple of hours to the goods.
There is some camping up there, with creeks and streams to fish in, but a lot of it is private property, so be aware of where you are camping.
Nederland is going to be your best option. Go to the smokehouse and get some tasty sweet potato fries and a brew!
Be on the lookout for private property signs.
