Rider questions

Q: What's a good route to take
A: OR... From the parking lot: Take Edwards Creek Trail to WoodRat Trail. Woodrat to Soaring Eagle Trail. Soaring Eagle to Sugar City Trail (fun). Sugar City to Big Valley Trail. Big Valley to Chorus Frog Trail (?) to Tree Frog Trail which spits you out near Big valley again. For those who are happy to climb you can start the loop over again at the top of Sugar City Trail. I usually do Tree frog once because the climb to get there is no joke.

    Soaring Eagle is a bit rough right now. Some overgrowth but not enough to keep me away.
    Sugar city was regraded and this caused significant damage to most of the trail. It's extremely loose right now and many of the table tops are more like rollers now.
    Tree Frog is mostly in good shape. There are a few spots that are over grown and a few spots with rain damage (in the exposed areas) but still a blast to ride.

    Great trail and spectacular scenery on front half. Until tall grass is trimmed, do NOT go down the backside on trails like Sugar City or Big Valley, or you will hike your bike all the back up the hill like I did.

    Sugar City, Tree Frog Loop, Ware Trails are as close to flow trails that I have been on in this area.
    Nothing technical at all, a bit of exposure on them. The crux would be the slope, but nothing a beginner couldn't handle. If you carry some speed there are some small jumps that fulfill an adrenaline fix.

    Great downhills and scenery, but uphill climbs are HORRIBLE! Just be ready for them.

    Has so much potential, but it's really beat up as of May 2017. Needs another haircut since it has way too many weeds on the trail and really tall weeds beside the trail. The backside trail needs some smoothing out to allow riders to keep speed. The flow trail needs some jumps removed to allow riders to maintain speed. When in good condition, this can be a 3.5-4/5 course.

    I found Crockett Hills via Singletracks. I have ridden the flow trail @tamarancho and was excited about another "flow trail" in the East Bay.

    I was disappointed.

    The trails are not well marked. The area with the "Flow trail" is completely overgrown and damaged (cows, rain, run off, ).

    This has amazing views of the Bay. Its so wonderful to be in the hills away from all the hustle and noise, but not be too far out. The lower trails (from the Park Entrance, up) are okay.

    I am surprised the local councils that lobbied for the Flow Trail hasn't invested more energy in maintaining the trail.

    Not sure its even worth the trip.

    Cow hell:(. They have destroyed the trails two years in a row. Not worth going until dry and cleaned up.

    There are hard climbs, but the downhills and the flow trails within are great. It changes from the forest to open hills. Great place to ride, also, keep in mind, there are cows! :)

    I rode here with a group back in June, had an absolute blast! Yes the trail from the tunnel to to head is cow damaged but if you ride anywhere in the far east bay you are plenty used to that mess. The flow trail is the most fun I have ever had on two wheels, this was my first time on one so maybe biased. My entry level bike held up fine, although if you are a heavy rider and you have cheap disc breaks you better be careful on the final descent down to the parking lot.
    There were a few hikers along this portion as well. so Keep it under control on the last part.
    all in all if you live in the east bay this trail is a must visit.

    Cows have destroyed the first trail from the tunnel to the slab. Who let cows out there when it was wet? After all that work and very few places in the Bay Area where we can ride single track with dogs, sad:( the rest is fine, overgrown and tons of oak hanging over the trail off of the "frog " climb. Also one trail is closed for the Eagles again.

    Consensus was its a trail you may want to do once a year, due to the bumpiness, distance to trailhead. A lot of the trail getting to the flow trail is very bumpy caused by grazing cattle. The weeds on sunrise were over your head and ticks galore. I used leg warmers and deet spray I didn't find any as of yet. Trail maintenance is needed desperately. Tree Frog Trail was awesome. The trails ranged from dry to tacky with a few puddles here and there. A lot of cow manure getting to both.
    A lot of climbing of very long hills but the flow trail made t worth it. The climb out is rough! A lot of sun exposure. I wouldn't want to go when it's hot.

    Cow have destroyed trail between tunnel and sugar city loop. Loop is still good but watch out for rocks. Really muddy also. Climb back up is difficult because of the cows walking on fire trail. Had to go through grass to get around cattle and got bit by a tick. It is usually a fun ride but not so much this time. Tree frog loop is very muddy.

    Everything between tunnel and sugar city loop has been destroyed by cattle. Cows were everywhere. Climb back up from sugar city is even more difficult because of the mud and cows tearing fire trail. It need time to dry out and for cattle to move. Got bit by a tick also. Not a fun ride right now.

    My first visit to the park and I had guides who visit often. Starts out on a fireroad (Edwards Loop) at 8-22% grade which sets the tone for all of the fireroads and the reason riders pushed for singletrack flow trails. Note that the new trails are NOT on the official map yet but are off Sugar City trail.The initial fireroad becomes a wide single track that narrows as you reach the top climbing at 8%. At the intersection of Sugar City trail the new single track starts to descend. The trail was dry but not dusty and followed a ridge that may intimidate those who do not like drop-offs. There are added table tops and berms around the many switchbacks. The table tops are 8-16 in high, not the 10ft mtn bike park type, so would be good practice for beginners other than the fact that the trail is only 18in wide with steep drop-offs. At the end of the trail the 20% grade fireroads have to be taken to return although during the week one can take the singletrack back up, too much weekend traffic to make this feasible

    Cows cutting up and down sugar city flow trail causing erosion. Super dry and trails splitting with cracks. But still fun:) best ride around these parts.

    Cows have done some damage. Dry and slick in sections. Wonderful views, great for family. Fire road climbs, not easy... Bring water.

    Not a bad mountain at all! Enough single track to keep you interested and wanting to come back for more. The fire roads are indeed steep, but the reward is worth the climb. Girl707

    This is a big park. Tons of uphill fire road, with lots of good flowy trails. Be prepared for a lot of climbing, with singletrack in between climbs. Nice place to go on a colder day...because when it is hot, it will be very tiring.
