South Saint Vrain Trail is a 4.8 mile moderately trafficked out and back trail located near Nederland, CO that features beautiful wild flowers and is rated as moderate. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible from March until October.
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.
