Went here instead of a trailhead at Brainard Lake due to the traffic and line to get into the rev area parking lot. We ended up doing the 12 mi round trip from this trailhead to the lake. Lightly trafficked. Good trail markings. Dense forest. It got a little dicey when a bad storm hit us... lightning and hail in the forest is pretty intense, especially with a dogger. We ran into a couple of mountain bikers who had varying degrees of courtesy. If you’re avoiding MTB’ers, this trail may not be for you.

I hiked this one as an overnighter this past weekend. After the 3 mile mark there was considerable mtn bike traffic. There are a few epic waterfall overlooks just before the intersection with Sourdough trail with Wilderness camping an options from near there until the second stream crossing. Lots of downed trees in this area with many blocking the trail. The first 3 miles is a patchwork of private land with evidence of heavy moose presence. At trails end you only have a short walk to the Long Lake trailhead and only 1/4 mile on to the lake. The return trip is a breeze being 98% downhill. **I am not sure why but the map here only represents the first half of the trail. THis trail continues to within a half mile of Long Lake.

Great dog friendly hike with a stream that runs alongside majority of the first part!

I started fairly late - around noon. Parking was fine, it's just off the road. Not too busy, but I did see a number of people hiking and a couple biking, especially on the way back. Definitely not crowded though. This trail is mostly shaded with a couple of meadow areas. Lots of Aspens. There's a couple of places to go down to the creek. Eventually, you meet up with another trail (USFS, Boulder County?) that's a gravel road. There's a wooden bridge here, too, with a USGS stream monitoring station. There's a couple of inclines near the beginning of the trail, but nothing too crazy and it chills out after that. A few rocky parts to the trail, but nothing crazy. I'd do this one again, for the shade and creek alone, but there's nothing terribly notable about it.

This trail is a gem. Just enough scampering over rocks, logs and perfect mountain meadows with aspen stands and deer. Well marked also. I am going to do this one again

This is a pretty, woodland trail, accessed off HW72, on CR 96, the road to the boy scout camp. It follows along the South saint Vrain river, with some steep areas and some very easy areas. I didn't get too far, as I had started late, but will definitely come back for a cool hike on a hot summer day, and in the fall to enjoy the impressive stands of aspens. It leads to the Wapiti and Sourdough trails, as well as to Brainerd lake. Dogs welcome. It is not the Ceran Saint Vrain trail, as the picture above erroneously implies.
