Pinto Rock is a silicified tuff-breccia formation NE of Mt. St. Helens. There are many knobs and projections welded into its tuff giving it the appearance of conglomerate concrete. The rock quality varies depending on the route and the use. The formation is split into two summits, the south being the tallest at 400ft.
Pinot Rock is a good alpine rock experience. Routes range from 5.0 to 5.8. There are 4 documented routes and one that is undocumented and bolted. There can be much rock fall due to the infrequent climbing. Route finding is also difficult.
To get to Pinto Rock drive I-5 to highway 12. Drive east on 12 to Randal Washington. Turn south onto 131 and follow to FS25. Follow FS25 to intersection of FS25 and FS28. Turn left on FS28. Follow FS28 and turn left on road 77. Follow 77 up the hill and stay right at the 224/77 Y intersection. Park in the large pullout on the right at a left bend in the road. Pinto Rock is visible north of the parking lot and can be reached by a very evident trail to the north. At the base of the rock take the left trail to the routes documented in the Beckey Guide. Take a right to find the bolted route.
No permits are required for this area.
Free camping in the turnout is convinient. There is no water or coverage in this area so bring everything you need.
Climbing during the summer and fall is best. The area is inaccessible during the winter and spring due to snow.
