Features Views


A variety of singletrack, doubletrack, and fire roads that offer technical climbing, flowy descents, and beautiful scenery. Marshes, meadows, forests, a lake, some wildflowers, and (in the Spring) even a creek or two. Be sure to BRING WATER.

Need to Know

Parking is free at the Channel Lot, but if that fills up there's pay parking at the horse staging area where Channel Trail meets Warren Richardson Trail. Stay on Channel Drive to get there, but do stop and pay at the ranger station on your right side (halfway down the road).

BRING WATER. It gets hot here in the summer and there is no water available on the trails. Mornings here are often foggy, which makes for cool vibes and cool temps (if you're here early enough). Springtime is ideal here as there are creek crossings and everything is green and lush.


This route starts and ends at the popular Channel Drive parking area (arrive early if you want a spot). Bring water, as there are basically no water fountains.

Channel Trail is a nice warm up, followed by an easy but beautiful climb up the Warren Richardson Trail. Next is the Two Quarry Trail climb, which is challenging due to the baby-head sized rocks and a couple of tricky obstacles. Take a right at the "top" to continue on Two Quarry Trail until the left at Marsh Trail. Things are pretty and mellow here for a bit.

Take the left onto Lawndale Trail, which starts out flat but turns into a fun gradual and flowy descent all the way down to the road and parking area (you can stash additional water here in advance if you're able). Turn right on Lawndale Road for a gradual road climb until the road splits. Take the right split onto Schultz Road, which winds through the neighborhood. The Schultz Trail trailhead is on the right (look for the gate).

Schultz is a beautiful, but challenging (at times) climb due to baby-head sized rocks. At the next split, take a left onto Ridge Trail which will take you all the way to Marsh Trail. Take a left onto Marsh Trail for a gradual, sometimes rocky, fire road descent that connects to Canyon Trail. Take the left onto Canyon Trail for more rocky fire road descending all the way to the bottom. When you cross the wooden bridge make a right and climb up Spring Creek Trail. This is a beautiful technical climb with a lot of foot traffic. When you pop out into the open, stay to the right and get ready for the more challenging half of the climb.

At the top of the climb (the lake), go left and make the first right onto Lake Trail, which is a flat ride along the north side of Lake Ilsanjo. Make the left onto Louis Trail, which is mostly climbing and has a few rocky/technical bits. Before long, this will link up with North Burma Trail (once the dirt turns red) and it's GAME ON from here. North Burma starts out flowy, but once you hit the "T" you'll turn right for some downhill action. Burma spits you out onto Channel Trail, make that left and you'll be heading back to the parking area where you began.

*For a slightly longer option, you can add 3 or more miles and 300 feet of climbing to this route if you add in the Rough Go Trail to Orchard Trail Loop after the Spring Creek climb.
