Cow Hollow Park operates year-round as a county-managed campground located on a dead-end road about 15 minutes from Nyssa. The facility sits on grounds with significant history, having served as a stop on the Oregon Trail, a CCC camp, and later a Japanese internment site during World War II. The park functions more like a city recreation area, with two baseball fields, playground equipment, basketball and tennis courts, and a horseshoe pit spread across a large grassy area.
RV sites line up side-by-side on gravel, with hookup options varying by location. Electric pedestals offer 20, 30, and 50 amp service, though some reviewers note the equipment shows its age. Water connections require longer hoses to reach certain sites, and full hookup spots are limited to just two sites. The bathhouse provides hot water for showers, though maintenance varies and cleanliness receives mixed reviews from campers.
Pricing creates some confusion, with rates ranging from $5 to $30 per night depending on hookup needs and conflicting information between online listings and on-site signage. MeLinda W. notes the flat rate applies "whether you use water & electricity hookups or just park." Camp hosts live on-site, though availability for check-in can be inconsistent.
The location provides access to Snively Hot Springs about 12 miles away and serves as a base for exploring the Snake River canyon country. For additional camping options in the region, campers can find sites near Adrian.
