Castle Rock Zip Lines and Aerial Trekking
Town Council approved a lease agreement with Royal Gorge Zip Line Tours. Castle Rock Zip Line Tours opened at the park in 2015 with the opening of the EPIC Adventure Tower.  Then in 2016 they added the EPIC Sky Trek Aerial Trekking as the final amenity to the park.  The Town has no financial investment in the zip lines. However, the lease agreement grants the Town 5 percent of the gross revenues.
