From the northeast corner of Henry Cowell Redwoods State Park, Graham Hill Trail starts via Pine Trail. Spanning 1.3 miles, this trail gradually loses elevation as it heads south paralleling Graham Hill Road. Shortly after starting down this trail you will cross the entrance to the Henry Cowell Redwoods Campground.
This portion of the park is mostly devoid of redwood trees, and pine and oaks dominate the forest instead. Fungus is fairly abundant at the southern end of the trail once you've made your way back into the redwood forest. The trail ends a mile after passing the campground. Powder Trail continues where Graham Hill ends. This trail will take you to Pipeline Road or down Buckeye Trail. This is a dog-friendly trail that stops at Powder Mill Trail.
