You can get your Oregon state park camping fees refunded for a stay while you were on leave. Unlike veterans with a disability, who get a pass, you pay up front and then claim the money back. The refund covers RV sites, tent campsites, standard horse campsites and day-use parking, but not yurts, cabins, special park facilities, reservation fees or fees for a second driven vehicle.
Post your refund request within 30 days of your stay to the Oregon Parks and Recreation Department, ATTN: Veterans Pass Program, 725 Summer Street NE, Suite C, Salem OR 97301. For help call 800-551-6949 or email special.access@oprd.oregon.gov.
A receipt for the dates of your stay, and a letter from your commanding officer on official letterhead stating you were on leave when you were camping.
