Climb Route (Untimed): Start at Mountain Bike Parking lot. Climb up road to Upper Notorizer. Climb Upper Notorizer into Vedder Climbing Trail. Climb up Vedder Climbing Trail. Climb up road to entrance to the Den. The timed section will start at the top the Den. NO SHUTTLES!!!
Not really prevalent mud as the rating says. Trail is good for about 90% of length, but run-off creating 2 or 3 deep (over the shoes) mud quagmires despite awesome trail drainage and log corduroy efforts by trail builders.
