**Overview & Facilities**
Ontario State Park offers year-round day-use access to the Snake River just north of Ontario, Oregon. The site features a two-lane concrete boat ramp (located past the first parking lot) and separate raft launch/takeout facilities. The park includes modern restrooms, green grounds, and picnic areas, making it a comfortable staging point for river outings.
**River Character & Boating Conditions**
The Snake River at this location is a major waterway—a stream order 9 river averaging nearly 50,000 cubic feet per second with an average velocity of 10.81 feet/second. The river descends significantly across its 559-mile length with an average gradient of 15.8 feet/mile, indicating moderate current and dynamic conditions. Paddlers and boaters should be prepared for swift water and plan accordingly. This is a popular section for the Snake River Water Trail, with the park serving as a key access point for multi-day trips.
**Planning Your Visit**
Both the day-use area and boat ramp are open year-round, making this a reliable launch point for spring, summer, and fall paddling seasons. The site is managed in partnership with federal and non-federal agencies to support quality recreation. Check current river conditions and flow rates before launching, as the Snake River's high average flows demand respect and proper safety preparation.
