Set along the Columbia River just east of Umatilla, Hat Rock State Park is one of the region’s most recognizable landmarks, named for its distinctive, hat-shaped basalt formation rising from the desert landscape. This easy-access state park offers a perfect blend of scenery and recreation, with picnic areas, a campground, and a boat launch that makes it a favorite for fishing, kayaking, and water sports. Walking paths wind through open terrain dotted with native vegetation, while the riverfront provides sweeping views and excellent birdwatching opportunities. Notably, members of the Lewis and Clark Expedition passed by this striking formation in 1805, documenting it as a landmark along their journey west, adding a layer of historic significance to its natural appeal. With its unique geology, sunny climate, and relaxed pace, Hat Rock State Park is an ideal stop for travelers looking to experience the natural beauty and outdoor lifestyle of Eastern Oregon.
