The Ah-shi-sle-pah WSA is located 60 mi south of Farmington or Bloomfield. It’s an 1.5 hour’s one way drive, first along Hwy 371 until milepost 61 then following CR-7650 for 7.8 miles. Turn right onto CR-7870. After another 9.4 mi you’ll arrive at the junction with Hwy 57. Turn left and 2.8 mi further down look for a track leaving the road on the left side. Leave your car here and follow the trail for 0.6 mi to the old official parking place (before 2011) and further north until you reach the rim. The trail is not marked on common topographic maps, but you can easily find it on Google Earth. Coming from Farmington you’ll need to drive 20.5 miles on dirt roads. But CR-7650 and CR-7870 are usually passable for normal passenger cars and well maintained since they are regularly used by the big trucks of the Bisti Oil Field. Nevertheless be aware that these roads can easily turn into a “mud trap” after heavy rains.
Ah-shi-sle-pah can also be accessed from the East. Head south on Hwy 550 from Bloomfield, turn right on Hwy 57 at the Blanco Trading Post (mile marker 123.2) and continue southwest for more or less 18 miles until you reach the unsigned track to Ah-Shi-Sle-Pah on your right hand side.
