I found a way to connect to the Bonneville Shoreline Trail from Highway 6, at the mouth of Spanish Fork Canyon. Just east of the monstrous windmills you will see a horseshoe pull-off on the left (north). There is a vague, steep and rocky double track trail that climbs to a power line trail. It's just over 1/4 mile to the trail (.29 to be exact). This is a good, wide roller coaster trail that goes for about 4 miles until it meets Mapleton Canyon.
