I took the Big Rock Ridge trail all the way to the radio towers. This hike meandered through a mixed range of elevations and had fabulous views of overlooking the Skywalker Ranch, and on the top I could see as far as San Francisco.

Once at the peak, you'll experience great views and have the option to go down numerous offshoot trails.

A little more challenging than I thought it was going to be. A good charge up hill.

While it says easy, it is a pretty good clip uphill. It is very close to my place so I will definitely go again, but I may not go the full way to the radio tower. I think I would instead turn around at the spot about halfway through where you are overlooking Skywalker Ranch.

Sat Jan 31st - got WAY over ambitious and spent 6 hours on this trail - dangerous for my stage of health-- up Big Rock - to the tower then up to Luiz trail - total of 4.5 hours climbing up - then 1.5 dangerously steep downhill gravel road - collapsed at end of trail -- won't try this again for at least 6 months!! Yikes!..
