Dyer State Wayside is a small Oregon roadside park about 10 miles south of Condon on Oregon Route 19, in a narrow canyon along a branch of Thirty Mile Creek at the mouth of Ramsey Canyon. Covering 0.6 acres, it provides picnic tables and public toilets. The land was donated to the state in 1931 by J.W. Dyer, for whom the site is named. After falling into disrepair, it was revived beginning in 1997 by volunteers known as Dyer Partners, who cleared and repaired the grounds, planted trees, and supported later upgrades including donated toilets, new vaults, irrigation, and improved paths and parking.
