The route is mostly cross-country, following the San Luis Rey River.
Expect smooth rock, brush and a steep drop at the end.
How to get here:
Exit Hwy 79 close to mile 37 on the 9S05 "Indian flats road" also known as Lost valley rd/Lost Creek Rd.
Drive this excellent narrow asphalt road up to the campground.
A nice detour is to continue on the main road, which is now a dirt road.
At the unmarked 3-way intersection, turn right and go through a gate that will eventually lead to Chihuahua Valley Rd.
The road to the left is a one-way street with a gate at the end.
