Friends of the Columbia Gorge generally offers a guided tour of the pictographs and petroglyphs every spring and fall as part of our seasonal guided hikes and outings schedule. You can also go online to register for a tour offered by Washington State Parks Staff at Parks-She Who Watches Tours. For groups larger than 20, call Goldendale Area State Parks at 509-773-3145. Tours start at 9 a.m. on Fridays and Saturdays, April - October. You may want to plan ahead by two to three weeks, as tours fill up fast.
