There’s nothing more scenic than traveling the Columbia River on the Washington side (State Highway 14) and this is a great place to stop for the night and get some exercise .
Going east on State Highway 14, cross US Route 197 and 4 miles beyond you will see the sign for Columbia Hills (It use to be called Horsethief Lake State Park and some maps still list it as such) Milepost 85.There are 8 sites with partial hookups for RVs up to 30 foot, but I think larger rigs would fit in most of them. Water, 15 amp electricity, tables, fire grills and a dump station are available. Boat launching facilities are located right outside the park and very accessible.
We really enjoyed the petroglyphs and pictorgraths alongside the trail to the river. They were removed before the lake was flooded and the Native Americans come to the area to worship. We were unable to see She-Who-Watches as the trail was closed due to vandalism, but during the summer, on weekends they do have tours and we will be going back for that.
