Uncompahgre Blue Lakes Pass is accessible by foot on the eastern edge of the Mount Sneffels Wilderness Area .
East access is via wildflower-filled Yankee Boy Basin.
The pass divides the waters of East Fork Dallas Creek to the north and Sneffels Creek to the south. The San Juan Division of the Hayden survey holds the record for the first ascent of Mount Sneffels, in 1874. The earliest known regular use of the pass was around 1917, as a pack trail. The pass is a narrow, sharp saddle between Gilpin Peak and Mount Sneffels, with rocky ridges extending off each mountain. Look into the Mount Sneffels Wilderness Area to the west, then look northeast to Teakettle Mountain and the little Coffeepot Mountain.
