As part of the new development along Ingle Road, a trail is being developed through the development and along the side of Green Mountain. Eventually, as further developments are completed, more trails will connect and lead to the Clark County Legacy land on the top of Green Mountain. As of now there is no public access to that land. The trails within the development allow for a little under a mile of paths.
The connection to the trails on Green Mountain from the development has been made. Just park by the pool and follow a path to the NW.
