Bonneville Shoreline Trail, Recreational trail in Utah, US

The Bonneville Shoreline Trail is a network of paths in northern Utah that follows the ancient shoreline of Lake Bonneville. The trail winds through mountain slopes, forests, and residential areas, offering different sections for various skill levels and interests.

The trail's name comes from ancient Lake Bonneville, a pluvial lake in northern Utah that drained about 14,000 years ago. The route was conceived in 1990 to link and protect existing trails above Salt Lake City, and the Bonneville Shoreline Trail Committee was formed to promote it. Utah recognized it as a Millennium Legacy Trail in 1999, the same year bridges were built over I-80 and I-215 at Parley's Canyon. By 2024 the official trail totaled 173 miles in about a dozen fragments.

The trail links neighborhoods to natural areas and is maintained by local volunteers who care for it regularly. People use it as a daily route for walking, running, and exploring the landscape near their homes.

The path passes through different elevations and terrain conditions, so bring appropriate footwear and gear depending on the section you choose. Many parts lie near roads and neighborhoods, which makes it easier to enter and exit, but also means some areas can be busy.

The trail's planned route runs over 350 miles because it weaves in and out of Wasatch Mountain canyons, even though its termini at the Idaho border and Nephi are only 150 miles apart. It passes within 20 miles of 80% of Utah's population.
