Maryhill State Park sits alongside the Columbia River making it a popular summer destination. We visit the most in February though when we do a Gorge winery tour for Valentines Day. The park is open year-round and we enjoy visiting in winter when we have the park nearly to ourselves. We have stayed in many sites, most often site#33. A word of caution- The railroad tracks are close to the campsites and trains go by throughout the night. If you are a light sleeper you may wish to bring earplugs!
