From the center of town in Buena Vista at the US285 and CR306 intersection, drive south 8.1 miles south on US285 and turn right onto CR162. If coming from Johnson's Corner, drive south 5.7 miles to CR162. This is also known as "Chalk Creek Drive" and heads up towards the Mt. Princeton Hot Springs and takes you below the spectacular Mt. Princeton Chalk cliffs. Drive west on this road for 12.5 miles to the townsite of Alpine. Directly across from Alpine Reservoir is the turnoff for FR277 that heads up Baldwin Creek. There is very limited parking here. You may be able to find some parking around Alpine, but most everything is private property, so be careful where you park.
It is possible to drive up the Baldwin Creek road if you have 4WD or 2WD with good clearance. Every time we've been on this road (and that's quite a few), we have found it tediously rocky and slow and with more and more 4WD's, ATV's, etc., it is not likely to improve. This trailhead will be somewhat unique in having an "Upper Trailhead" as well. This is where FR277 and FR278 split with FR278 heading off to the left (SE) and immediately crossing Baldwin Creek. FR278 heads up onto Mt. Antero and eventually crosses over into Browns Creek. FR277 continues SW up along Baldwin Creek to a switchback where a trail to Baldwin Lake heads off. Trails Illustrated shows the road ending there now as does the Foreset Service map. The coordinates for the FR277/FR278 intersection are N 38° 40' 57.11 W 106° 16' 22.56". Elevation there is 10,870 ft. The distance from the lower TH is 3.0 miles.
Near the FR277/FR278 intersection, there are some limited, primitive camping opportunities. Drive just a short distance farther on FR277 toward Baldwin Lake and there is a good area with multiple campsites at the coordinates provided below. There are also some good primitive sites on FR278 just after crossing Baldwin Creek.
