Rebecca and I went hiking at Maple Pass Loop a couple months ago. It's about 7 miles around the loop, and there are great views into the North Cascades from the top of the pass.

Near the top of the pass we got caught in a rain shower. We quickly hurried over to the east side of the pass, where the wind was calmer and it was warmer.
