This little segment of trail is the best part of riding at Lake Castaic. It's fun, fast, and not overly difficult. There are a few small jumps and a couple of small berms. There's nothing technical, just pure fun.
Climb up the Pro's Uphill
trail until you get up to the green box. Veer to the right at the box and you're golden. You'll cross the a fire road once on the way down, just hop back on the trail and you'll finish near the West Ridge Trail
