This is the downhill part of a small loop around the Guadalupe Reservoir up to the Almaden reservoir. For that you need to climb the Hicks Rd up to Alamitos Rd. Super steep and painful :-) and the downhill is kinda scary too.
did you go all the way up? i think i came down the same road today but i thought it was much steeper while i was riding down. it was a very scary descent. I am new to cycling and even had to step off my bike at a couple of points because my hands were cramping from slamming on the brakes. nice ride.
