Maryhill / Bridge Here's the crossover from Oregon to Washington at Exit 104 off I-84. Take HYW 97 North to the first Intersection. Then go Right on HYW 14. Pass the Stonehenge access road until you see Loops Rd. on your left. This is it, follow this and DO NOT go into the property entrance on the left. Stay on the road curving right and then back to the left where there is a parking to park and begin the hike up.
