DIRECTIONS
Our campsite is nestled in the towering pine trees in a scenic spot at about 8500 feet elevation. Situated between the communities of Red Valley and Lukachukai, the site is just east of Buffalo Pass overlook in the northern Chuskas. Below are the directions from a variety of locations.
From East:
If traveling from Shiprock, Durango, Farmington, Cortez, T’iis Nasbas, etc., head south on U.S. Highway 491 out of Shiprock. Five-plus miles south of Shiprock will be the junction with Navajo Route 13, with signs indicating Red Valley, Cove and Lukachukai. Turn right and head west on N13. You will see the Red Rock Trading Post and school in 22 miles, then will pass by Red Valley Cove H.S. and NHA housing on your way to the mountain. About twelve miles from Red Valley you will arrive at camp, which will be visible on the right (north) side of N13.
From South:
Travel 60 miles north on Navajo Route 12 from Window Rock, Ganado, Gallup, etc. to the junction with Navajo route 13 at Lukachukai (aka “L.A.”). From LA, head east into the mountains. From the junction, you will travel about 12 miles to Buffalo Pass, on your left as you approach the summit. Continue one mile east of the Pass to our camp, which will be visible from the highway on the left (north) side of N13.
From North:
Travel east eight miles from Kayenta on U.S. Highway 160 to the junction with Navajo Route 59 at the top of Church Rock hill. At the junction, turn right and head south 44 miles – past Chilchinbeto and Rough Rock en route to Many Farms. At Many Farms, travel 16 miles east to Round Rock on U.S. Highway 191. At the Round Rock, turn right and head south on Route 12. Continue 15 miles to Lukachukai. From Lukachukai, head east on N13 toward Buffalo Pass. Camp is just one mile east of the pass on your left (north).
