If coming from the northern Front Range areas or up from Boulder, drive to Nederland and from the traffic circle where the three main roads intersect, drive south on SH119 .7 mile and turn right (west) onto CR130 to Eldora. If coming from the south by way of SH119, this turnoff will be just south of town just after a couple of switchback curves in the highway drop you down to town level. Turn left (west) and drive to Eldora on paved road, passing the high school and the turnoff for the Eldora Ski area. From Sh119, it's 1.5 miles to the ski area turnoff. Continue through the town of Eldora where the paved road ends and continue in a NW direction on CR130 to the Fourth of July Trailhead and campground which is about 7.6 more miles. The road becomes progressively rougher but does not necessarily require high clearance or 4WD, but you might be more comfortable with a higher clearance vehicle at least.
There is a small campground and a trailhead parking area above. There's a vault toilet available.
