Great day hike near Boulder/Longmont/Lyons. Light usage, could be a bit confusing to arrive at trail head. See Getting There. The trail head is on the left-hand side of the parking area. There are MANY trail options here, so take care of which trails you take to ensure you end up where you mean to! This map will take you on just the out/back Coulson Gulch trail. Mostly downhill on the way out, so keep in mind the way back is where the "intermediate" comes into play. Approximately 1.8 miles into the trail lies an old abandoned cabin, nice place to stop for a snack/water/shade break.

One of my favorite hikes in Lyons! The first section is pretty well shaded, however, once you get to the meadow you're pretty exposed. We were hoping to make the loop to button rock and then on to north sheep mountain, but unfortunately due to the flood, we were unable to pass the St. Vrain, as the bridge has been washed out. It was still incredible hiking to the river at peak run off season though! A four wheel vehicle is definitely required if you're planning on parking at the trailhead. Overall, really enjoyable. The hike in is mostly downhill, so don't forget you'll have to climb your way out!

Absolutely beautiful. Good workout but doesn't kill you, views are spectacular and it is amazing to hear nothing but nature around you. Not crowded at all. We will definitely be back soon, probably my favorite trail in Colorado so far.

Beautiful forest with a large Meadow. The trail follows a seasonal stream. I wasn't able to complete the loop around Sheep Mountain because the river was impassable. Beautiful though!

I loved this trail. Wife and I hiked it in the afternoon; mid-May. Several very small stream crossings, a large beautiful meadow. The majority of the hike follows a small stream. There are stretches where it feels as if the forest is collapsing on you. I think we only saw 6-8 people throughout the entire hike. Small climb at the end but nothing too taxing. I would definitely do this one again!

Great trail! Was the only one on the trail so almost was a little eerie feeling because definitely in bear / mountain lion country....so keep your eyes open! But very well groomed and a nice peaceful stream that runs along side it. The last 0.5 mile of the road to get up to the trailhead requires either a high clearance or a 4WD car. I parked at the bottom of the turnoff which was fine.

Overall good hike. Trail is still closed, but the area is beautiful.

If you have a vehicle with decent clearance then bypass the road hike. The trail itself is mainly loose gravel but pretty easy going. The trail is still closed about 2 miles from the trailhead.

Beautiful trail. The way in is mostly down hill so conserve energy for way back. Beautiful meadows and wild raspberries are everywhere. My fingers are red. Recommend this hike to all. Careful on downhills its dry dirt with some wash out. Can be a little dangerous for small kids without proper shoes. Pack in water you will need it for way back. Great hike. Absolutely beautiful vistas. Others have bypassed the closure two miles in. Not recommended to go off trail but with good gps and some knowledge of trail hiking the closure can be bypassed and you can go through to button rock.

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!!
