Need to Know

You cannot park at the dirt must climb through neighborhoods to access. You can get a speeding ticket on the descent but it's rare. You can also get a ticket for not wearing a helmet as well as for wearing headphones.


There are no big walls to contend with...just a steady grind. This ride can be very hot with loose dirt in the summer - there's little in the way of shade. It's definitely more of an 'exercise ride' with a long, sustained climb to top.

A LONG climb and a dexcent that should be faster, but isn't. Rocky and pretty, but also rutty and twisty. Mostly LONG.

Park closes 1/2 hour after sunset. Hefty fine if you get caught by rangers. Mine was $234 in 2014. Oct 2, 2014

Tried to ride this last week and turned around due to construction going on near some water tanks and the road is closed beyond that. There are private property/no entry signs posted everywhere above Madrone Ave. as well. Feb 12, 2016
Started from downtown Los Gatos and rode to the top where the benchmark is. The ride up through neighborhood streets is a mix of sun and shade. I ignored the 'Private Property, Keep Out' signs on La Mirada just before the water tanks since other, park signs indicate hikers and bikers are granted a right to pass. Once you're in the park the first 1/3 or so of the ride up is on a nice fire road which is shady. Then you break out into the blazing sun for a couple of miles on fairly rocky and somewhat steeper terrain before getting back into some welcome shade for the final 1/4 of the ride to the top. There are nice views at the top. You can see Silicon Valley, Lexington Reservoir and Monterey Bay. Oct 13, 2018
