Roger's Grove Nature Area consists of 54.9 acres adjacent to the St. Vrain Greenway and includes Fairgrounds Lake, trails, a shelter, outdoor amphitheater, restrooms, native landscaping, demonstration gardens and an apple grove with fruit free for your harvest! Design and construction of the nature area was primarily funded by the Roger and Roberta Jones Foundation. Roger Jones (1915-1995), enjoyed walking along the river with his wife Roberta (1913-1992). Both educators in the St. Vrain Valley School system, the Jones' wanted to contribute an environment for children and adults to visit, learn and enjoy. Roger's Grove was developed as a nature area, arboretum and outdoor learning center. Additional funding came from the Colorado Lottery and Great Outdoors Colorado.
