From the intersection of Wyoming Boulevard and U.S. Highway 20-26 in Mills, west of Casper, follow 20-26 west 1.5 miles. Turn south—left—onto Wyoming 257 and follow it for 1.2 miles. Turn right, and after .1 miles turn left onto Poison Spider Road. From there it is 7.1 miles to Emigrant Gap. The road is gravel for the final 1.6 miles, plowed in winter and in summer easily passable in dry weather. A Bureau of Land Management interpretive sign marks the site.
