We'll do this on a weekday to limit the competition with ski traffic. After setting up car shuttle as a group, we will do a one-way hike gradually uphill, with optional short rewarding side trip to Skookum Falls.
ALL participants signing up for this hike must agree to help coordinate the care shuttle
