Took my 8-year old on his first "real" mountain bike ride here. This is a great place for an intro to riding singletrack - a few roots to maneuver, but mostly smooth redwood dirt and and nothing too steep.

Trail Rd 508
Detour from the road below it, little more elevation change id say than the road. More fun I’d say, adds time whichever direction you’re going. Old road that just had singletrack worn in now

Trail is open. Major pain going up, pushing half the way. Good to go down of course. Wouldn’t say its better or worse to lose elevation on than ez out, just different. End up on road 410, anywhere you go from there is up.

I can only speak for the western half of the trail where it meets up to a bunch of other trails in the middle. It’s a scenic fairly flat ride, good views of the river, easy to carry speed either direction. Kind of a road, kind of single track in spots. Would be a good beginner, xc, or gravel ride. Your wife or child could enjoy this, just pick a distance you want to go

Decent spot to ride up from big river rd to get to mo betta trails to go down. It’s a climb. Can only be so much fun. There’s better trails to drop elevation on I’d say

Flatter and less densely wooded than the rest of the forest. The single track splits a few times in different directions, I guess some is private property

Good to connect with the ride thru stump in either direction. Nothing too techy, just a fun ride. Not too fast, not too slow. Just about right. Be sure to say hi to the invisible man cooking bacon on his bbq

Can go either direction, kinda steep going up but you can do it, I believe in you. More fun coming down of course. And there’s a stump you can ride through and get cool pictures!

This is an easy trail that parallels the dirt access road. It is single track and gets a lot of use in both directions. It is not clear why it is rated blue. It should be green. In any case, beats riding on the dirt road.

Very solid route. Not too terrible elevation. Most of the singletrack parallels forest service roads so if you want to save some gas for later you can bail on a section and still stay on route.

The section EZ Out is the most technical singletrack on the route.

Not many views except near the top of Observatory Hill

This is not a trail, it is a crappy dirt road and if you are thinking you might make a loop with speedway, good luck. Don't waste your time. Stay on the trails south of Casper Orchard Road.

Pretty bad trails in this area. Gunslinger is ok ride through stump is a 2 star trail. Go ride the other area. Manley gulch area trails are 4+ stars. This was not worth our time.

Very nice ride in either direction, although a little more fun towards parking area since that direction has more downhill sections. Lush ferns and other foliage line trail and redwoods surround trail. Some sections have a bunch of roots adding a technical challenge but overall a fairly easy trail that can be ridden faster than many other trails in this forest that have much tighter trees.

Very pretty trail with thick ferns and redwood trees. Some rooty sections add a bit of technical challenge, but trees are mostly spaced away from trail allowing it to be ridden faster than some other trails in this forest.

Seems like private property and most of the attempts to get around failed. After looking around, continued to end of Mitchell Creek Drive then can work your way on rideable trails back to connect with the 2nd half of the trail.

Finding the Trailhead on the north end is challenging. It appears to start off a dirt driveway. We found it by hike a bike off the paved road.

there is a hard right turn that’s easy to miss, if you come out on an old dirt road, you missed it. the exit has some boulders and comes out on a well used gravel road.
