From Bailey, drive west on U.S. Hwy 285 for 14.3 miles. Turn right (north) off Hwy 285 onto Park County Road #60. This road is also designated as Forest Service Road #120, and is commonly called the “Hall Valley Road.” Travel on #120 for a total distance of 6.5 miles to the trailhead. The last 1.4 miles above Hall Valley Campground are very rough, and border on being classified as a 4WD road. Allow at least 50 minutes to drive the 6.5 miles on Forest Service Road #120. As you drive the #120 road, you will pass Handcart Campground at mile 4,8 (from U.S. Hwy 285), and Hall Valley Campground at mile 5.1. At mile 5.0, just before Hall Valley Campground, bear left at the fork in the road. There is a small parking area at the trailhead.
The Gibson Lake Trail (#633) travels in a westerly direction up the Lake Fork drainage. Just below the parking area, you cross the headwaters of the North fork of the South Platte River. The last 1.4 miles drive to the trailhead is very rough and requires high clearance 4WD to access.
