From the parking lot beside the freeway, take an easy but sun and wind-exposed stroll along the rim of the gorge. You'll first cross a footbridge that parallels the interstate, overlooking a stair-step waterfall within a corridor of vertical basalt. Continue along a paved path to find interpretive signs at another viewpoint, and go beyond that for a dirt trail with unprotected access to the edge.

You can continue along the rim, then cross a narrowing peninsula of rock to find a view over the voluminous natural spring––a pool of clear blue amid an amphitheater of stone. Just a little farther on, you'll see a hydroelectric dam at the confluence of canyons. From that point you can go no further, so you'll turn around and enjoy a different angle on the views heading back to the start.
