The Bonneville Shoreline Trail (BST) will one day stretch from the Idaho border to Nephi, more than 280 miles. Currently just over 100 miles of the route is officially designated as part of the BST. This website is a guide to the entire 280-mile proposed route. The route attempts to follow the Bonneville bench that was formed by the ancient lake. The route described here is not yet fully designated as the BST. The route may cross private property or other obstacles. Please be aware of signs, fences, and unmarked obstacles. This trail is a work in progress. It was started by citizens and will be finished by them with your help!
