Beginning at the intersection of FR603 and the Little North Mountain trail, ride past the gate uphill along the fire road for 1.3 miles along rolling to gradually upwards terrain.
Look for the singletrack trailhead on your left as you continue upwards through the gap towards the ridgeline. The trail will head upwards for the next 2.6 miles at a steady slog of 10-15%.
Just when you think you're at the top, the trail will continue to grind upwards. When you reach the intersection with Little North Mountain trail, either bomb back down to FR603 or continue to climb upwards towards Three Ponds Trail.
Although steep and steady, this singletrack climb is otherwise non-technical.
