The Bonneville Shoreline Trail is a ninety-mile long pedestrian and bicycle path for mountain biking which is being built across the foothills of the Wasatch Range along a route that lies generally on or near the eastern shoreline of ancient Lake Bonneville. Each city develops its own section as it sees fit. Provos section is a broad all-weather track that can be tackled in rain or snow, and its close to the city for an after-work or noonie bike mountain bike ride. While most of the trail is suitable for beginners, there are some steep loose sections where good balance and brake control are required. As a 6.8 mile out-and-back from Rock Canyon to Slate Canyon, it’s a nice workout. That s the good news.
The bad news: Provos version is -- except for a teensy stretch out of Rock Canyon -- an up-and-down jeep road. Much of the trail has been improved with a deep deposit of cinders, perfect for downhill bike-surfing and uphill trench-digging tire spinning. There are nice views over Provo, but the terrain is mostly grass with an occasional shrub.
Overall, Bonneville Shoreline Trail is the 37th most popular mountain bike trail of all 74 mountain biking rides in Utah.
