Mountain Biking Sly Park

****   Add a review
#48 of 999 mountain bike trails in California

From the trail head, the trail starts on single track through the woods, and frequently borders the lake. This single track session lasts for about 5 miles, and criss-crosses a horse trail. The horse trails are not open to bikes, and are clearly marked, so there should be no problem there.

After about four miles, right after a bridge spanning Park Creek, you will come to a cross roads. If you go right, you will come to a nice waterfall, and pool. This is a good place to take a cool dip on hot days, the pool is MUCH cooler than the lake! If you go straight at the cross roads, you will find a half mile fire road climb, rewarded by a fast fire road downhill with a couple of fun jumps. If a left is taken at the cross roads, you will take a rolling single track trail, which meets up with the fire road after about a mile.

Once trails meet up, you enter into the main park area, at the Hazel Creek campground. At this point, the trail goes in and out of the various campgrounds, and is in part single track, double track, and occasionally on the paved road. Keep an eye open for trail signs, as you go in and out of these sections. They are all marked, but it is easy to miss a turn, and have to retrace your route a little bit.

I usually camp here several times a year, and stay at the Hazel Creek campground. This allows me to start at the single track, and ride the trail backwards, and make it an out-and-back, with single track the whole way, instead of a loop.

Getting there
To get to this trail, take Hwy 50 East, from Sacramento, about 60 miles. At the second Pollack Pines exit, take a right, and follow the road until you reach the Sly Park entrance. At this point, if you have non-bikers with you, or are camping at the park, enter, and find a place to park, or your campsite. If you are just hear to bike, and don't want to pay the entrance fee, continue past the park entrance, and take a left onto the Morman Emmigrant Trail. Follow this road about a mile until you come to a hard right hand turn by the lake. There is free parking to your right, and along the lake. From this point, park your car, and ride along the lake frontage until you see the trail head immediately on your left.

    Sly / trail 8 / Flemming Meadows is a great quick loamy flow. Green trail, but a good amount of climbing.

    Just rode the trail on 7/18/2015. The trail is in good shape. Water level in the lake is fine. Bring non-biking family members along. They can play in the lake while you take advantage of the trail.

    Rode the trail on July 18, 2015. The trail is in good condition. Water level in the lake is decent. It was really low last winter but it is up now for summer recreation.

    If you have non-biking family members, this is a great place to take them along with you. They can hang out at one of day use areas and enjoy the water while you take advantage of the trail.

    Just rode the trail for the first time since the end of summer and the wind storm that went through the area a few weeks ago has left a lot of debris on the trail. But I have to say, for me, it made the trail even more fun! This trail has good flow and is a blast to ride....enjoy!

    What a kick ass trail. Talked to 5 local riders who told me to ride 8 trail counter-clockwise for the most fun. They were right! About a 2 mile climb followed by almost 3 miles of mainly killer downhill. Not very technical so its fun for most riders. At around 7 1/2 miles in there's some more really great downhill. Going again tomorrow and looking for some side trails to throw in

    Rode Sly Park for the first time this year. Trail is in good condition. I just wish they would build some options to skip some of the riding through the campsites.

    Bumpy Meadows is the El Dorado Irrigation District trail which goes around Sly Park Reservoir, also known as Jenkinson Lake. You can access the Bumpy Meadows trailhead from Mormon Emmigrant Trail Rd (past the second dam) parking is $5.00 0R park on Mormon Emmigrant and ride in for free!

    Part of the trail goes through camp grounds and is a fairly easy ride. The singletrack portion of this ride is true singletrack and not for beginners in more than a few areas.

    Logging in the area has made for some 'interesting' riding. It is easy to lose the trail in the first couple of miles from the Bumpy Meadows Trailhead due to the recent logging but this is also some of the most fun riding! There are some steep downgrades with loose granite rock so exercise caution....you don't want to hit these sections blind which can happen!

    The trail condition has deteriorated and needs some maintenance. It is definitely no longer a 'beginners' trail in some areas. I'll be riding the section from the Bumpy Meadows trailhead to the falls and back as an out and back on my next ride and will post more photos then. This seems to be the part of the trail that most 'air' people like. * Review edited 8/1/2012* Review edited 8/1/2012* Review edited 8/5/2012

    Nothing to technical on this trail, although I hit a rock section to hard, went over the bars, and wound up with stitches!
