Great 4x4 trail for high clearance vehicles. There are a couple of somewhat technical rock sections, but no problem for most light SUVs. Expect OHV traffic on weekends

Part of the trail is closed due to flood damage but there is still plenty of awesome trail to be covered! The trail is closed 2 miles after the ACTUAL trailhead (this closure is about 200 yards past the trail that breaks off to the east towards North St. Vrain Lake). Also, the trail as shown on the map is slightly inaccurate. "Johnny Park Road" is an unmaintained dirt road with significant washout. In bad weather without a great vehicle you will have to start where Johnny Park and County Road 47 meet. However, the ACTUAL trailhead is where this road meets Coulson Gulch Trail (at the circle shape trail). I was able to make it most of the way up in in dry weather in a 2 wheel drive Escape (and some fancy driving). Even if conditions prevent you from driving up, you could still park at the bottom and walk the half mile to the top as shown on the AllTrails map. Just know the road and trail are not currently clearly marked until you reach the top of the hill and the true trailhead. Enjoy!!

About half the trail is on a road. Nice once you get into the woods.

What's not love! I could see how someone could get off the trail. There are some foot paths leading off that if I wasn't paying attention could have taken a wrong turn. The views were great and it was a lot of fun.
