Coming July 29, 2015. Ride the dunes! Head to the Oregon coast for DuneFest, a fun, 5-day event. Held at Winchester Bay, smack dab in the middle of Oregon Dunes National Recreation Area, the largest expanse of coastal sand dunes in North America, DuneFest includes sand drag races, moto sport events, an impressive freestyle show, a treasure hunt for the whole family, live music, and loads of vendors with the latest in ATV and UTV parts and accessories, clothing, crafts, and food booths. Fun in the sand at the dunebuggy capital of the Pacific Coast!
