This is graded gravel at a very slight incline on the north section (nice fast descent if you have a south tailwind on the way back!), and dirt (sometimes rocky) on the southern loop portion, which has a couple fairly steep climbs. All in all this is a good gravel bike ride with some variety of terrain--flat vs hills, gravel vs dirt/rock. Passes by Vernon Reservoir where there are campsites and outhouses. Northern section is barren flatland and southern loop is juniper/pinion pine in the canyon and sparse juniper on the upper portion hills. Wider off road gravel tires recommended. Taking the loop counterclockwise recommended. Overall, there is nothing technical, although the road does get pretty rough in spots.
