Balanced Rock is famous throughout the Magic Valley, and getting there is easy. A picnic table and turnoff on Castleford/Glenns Ferry Road allows you to park below the rock. From there it's a short scramble up the hill to get to the base -- that's the only way to get a feel for the boulder's enormity.

Just a half-mile east down the road is Balanced Rock Park, with a few well-maintained campgrounds and a trout-stocked creek.
