Measure from the intersection of US550 and CO62 on the east side of Ridgway, turn west onto CO62, drive across the bridge over the Uncompahgre River, continue through town and go up the hill and continue for about 5.5 miles total to the turnoff for County Road 7 which will be on the left (or south side of the highway). Drive appx. 9 miles on this road to the trailhead. The road follows East Fork of Dallas Creek. The road is graded gravel and suitable for most all passenger vehicles, though there will be some rough spots to take it more slowly. About 2.3 miles in on CR7, the road forks. Be sure to take the right fork to continue on CR7. Do not take CR7A. The drive in is very scenic with views of Mt. Sneffels and the range of peaks on either side of Sneffels. In the fall, when the aspen are turning, this is a local favorite for beautiful photography. Shortly before arriving at the trailhead, there is an open filed on the right (west) side of the road where there is some primitive camping opportunities if you find the trailhead too crowded, which is often the case on summer weekends. The trail not only provides access to the Blue Lakes, but is also a popular route for Mt. Sneffels. There are no designated campsites at the trailhead, but several open spots alongside the road become impromptu camps and many visitors will car-camp here. Don't expect privacy.
As mentioned above, there is an open meadow area shortly before arriving at the trailhead where there is room for a number of primitive campsites. See coordinates below. It will be on the west side of the road. Otherwise, there is no forest service campground nearby and the only other option is at the trailhead. Most of the land you'll be driving through to reach the trailhead is private.
