There are many other remote places to boulder but this is the most popular. Only 10 miles outside of Bishop, it is easily accessible by going west on Hwy. 168 toward South Lake and turning right at Buttermilk road, approximately 7 miles outside of town. Continue west on the well graded, main dirt road for another 3 miles to the bright rock formations on the right. These are the Buttermilk Boulders and the road continues around the rocky boulder country to the Windy Wall and the Why Boulder.
Difficult routes abound.
These are sport climbs so they are generally well protected requiring a rack of quickdraws and some nerve. There are thousands of routes and there is a guidebook available at cliumbing shops everywhere. Head north on Hwy. 395 for 9 miles and turn right at Lower Rock Creek road. After 1 mile this road goes right toward the Pleasant Valley reservoir.
