I-90- Take the
Ephrata exit (Exit 151) just east of George and follow signs to
Ephrata. Turn left at 1st Avenue NW in Ephrata and drive
past the Courthouse. Stay on that road and you will cross a cattle
guard at the 15-mile point. ¾ of a mile past the cattle guard is our
main entrance, Sagebrush Dr., on your left. There are basalt rock
pillars on both sides of Sagebrush Dr. Follow signs to the
Campground/Office which is about 1 mile off the highway.
US-2- Turn south
on Coulee Meadows Road (note green and white Rimrock Meadows sign)
20 miles east of Waterville and 20 miles west of Coulee City. Drive 8
miles and look for an entrance sign on your right just past a brown
house with a green roof, also on your right. Follow signs to the
Campground/Office about 1 mile off of the highway. If you miss that
turn, you will come upon the entrance described above.
If you use Google Maps, the best address is
4177 Tumbleweed Way, Palisades, WA, 98845. It is not perfect but
close.
