From our Rivers page

Illinois River Forks State Park sits at the confluence itself, off US-199 just south of town. Oregon Parks and Recreation Department runs it as a day-use park, and its own listing showed it open with no day-use fee when we checked in November 2026. There's no camping.

What you'll find:

  • Picnic tables, a vault toilet, and a picnic shelter you can reserve for groups of up to 50 (800-452-5687).
  • A short walking trail and a 9-hole disc golf course.
  • Leashed dogs are welcome. Bring a bag.

Where the forks meet, a long, calm stretch draws summer swimmers. Rogue Riverkeeper, a river conservation group, tests the water there for E. coli every 2 weeks in summer and posts the results on Swim Guide. The sample from September 8, 2026 passed.

State Parks warns of swift currents and hidden obstructions under the surface, and asks swimmers and boaters to wear a life jacket that fits. Park info: (541) 582-3128, or see the park page.
