#238 of 1,001 mountain bike trails in California
#3,003 in the world

Flat wide trail around lake for warm up then head east up fireroad. Solid climb to antenna towers. Now the fun, lots of windy switchback single track all the way down to lake level. Alternate path, go up double track on north end of lake, to the north of look out parking lot, difficult climb to another antenna tower. At top take trail off back side (away from lake) and singletrack back to parking lot off of Alamo. If you run into a bridge followed by locked gate, don't worry retrace path southward and take first interesection to the right. Follow trail back to parking lot. Can't get lost on this ride. Good 1-2 hour after work fun ride. Lots of thorning weeds in summer but good year round.

Rider questions

Q: Is there a way to park at the top of you just want to ride the downhill section?

    This trail took some serious damage after all the rain NorCal experienced in January and February. It's still rideable, but many sections sport a deep rut from erosion. Moreover, cattle native to the park pock-marked the trail when it was muddy. Some sections Really test the suspension.

    The fire road leading up to the top of the trail is a really fun climb, and there are several other sections of single-track that get up the hills.

    "Beginner" is NOT a good rating for this park in it's current condition. It would be a bad idea to take an inexperienced mountain biker on this trail until the singletrack has had a chance to smooth out a little.

    In a way, the trail is more fun when it's beat up, it adds plenty of extra challenge and you feel like you're really pushing the bike to it's limits.

    Great single tracks with decent down hill for newer and intermediate riders. Trails get a lot of hikers and some horses.

    I'm new to MTBing spending the last 4 years running these trails. I feel this is a great place to learn how to ride! Lots of elevation and I love the down hills.

    Gravel road is steep. Single track can be tight and tough. Good work out.

    Ride is 4.6 miles from parking lot to
    Third Tower and back. No way to make this a 10 mile ride unless you loop the lake twice. Uphill is tough either on the fire road or the track next to it. 875 feet over two miles with a max grade of 12%. Downhill is narrow lots of switchbacks some exposure not really possible to really get good speed. I would say downhill is intermediate. Will not be back, your mileage may vary.

    Good ride if you are around a 30-45 min drive or less. There are several different loops to take. The one I find the best is to climb past each tower (microwave) until you reach the third one. Then take the single track downhill on the backside of that tower all the way down. It equates to about 20 minutes of downhill. There is also a fire road to the top. The sticker bushes are much better this year and have been pushed back from the edges of the trails.

    Took this trail twice in July. Went up road to the tower, which was a nice climb. Then, at the top, the trail goes into a single track all the way back. It was about 45 minutes up and 45 minutes down and back to the parking lot (free lot!). Problems: Too many stickers - first ride: one flat tire. second ride: both flat. Don't wear shorts - legs went through huge sticker bushes and at the end of the ride - my legs were bloody. A couple spots required walking. Overall, it is about a 2.5 out of 5 but I rounded up.

    I do not really like this trail. It is a great trail for running and hiking. Personally I feel that the trail is way too narrow. The ground itself is not too technical. Be careful, there are a lot of hikers on weekend. If I am in a hurry, I will do this trail. But I would rather do rockville than this one. After all, it is my personal preference. The fire road clib up to the antenna was good, though...
