There's trailhead parking for this trail right off of 41. Follow the trail down and cross the bridge. From there just follow the trail until it ends at Road 630 near Sugar Pine. From here you can turn left and cross 41 into the Miami Creek area or turn right and take Mill Canyon Road through Sugar Pine to Westfall Ranger station. If you turn right you can also make another right at Sugar Pine road to access Nelder Grove.
The trail is very well maintained with several small wooden bridges that are rideable. This is a multi use trail so be careful of hikers especially later in the afternoon. The entire trail is a faily dense section of woods so it is all shaded, an excellent place to ride in the summer.
