Fairgrounds Regional Park, Trail and Dog Park
Douglas County’s park at the fairgrounds: ball fields, a playground, a fitness court, six picnic shelters, an off-leash dog area and 2.66 miles of paved trail, with a trail into downtown.
The county park at the fairgrounds has three natural-turf baseball and softball fields and four more for soccer, football and lacrosse (three of them synthetic), a playground, a fitness court, six picnic shelters, restrooms and drinking fountains. There is a dog off-leash area, 2.66 miles of paved trail with a route on to downtown, and two lots for 342 cars. Groups of 15 or more should reserve, and hours can run later for night games on the lighted fields.
