Sly Park

 It's probably 50-50, with a big travel bike you will have to do some pushing. If you have a mid-travel bike you can ride the whole thing depending on your conditioning. In total it's about a 15 mile loop. It's not a super technical trail but it's still a blast, even on a big bike. It's located near Pollock Pines off of highway 50. If you just do a Google search for Jenkinson Lake Placerville CA, it should give you directions that are close. Once you get to pollock pines you can just keep going on the main road towards the lake until you hit either Mormon Emigrant Trail or Silver Lake Rd (not sure which one, I cant remember). Either way it's the first left after you pass the little gas station/store and you can only turn left onto this road. Once on that road a little ways down the road you'll cross the dam and the trail head will be off the the right maybe 100ft past the dam. There isn't a parking lot, just off the road parking. Once you're there just follow the trail out and it is pretty well marked. Just follow the trail signs. Watch out for equestrians and hikers, they have the right of way.
