From here, up the dreaded switchbacks! Bonneville Shoreline Trail, southern SLC
This trail follows the shoreline of Lake Bonneville for 3.1 miles, for a 6-mile out-and-back ride. It's narrow singletrack, easy on the south half, but technical on the north half. This loop ride uses the Hidden Valley singletrack and the Aqueduct trail. Season April through November. 
Trail conditions change, and the layout and connections of a trail will change. Use this trail guide at your own risk.

Getting there, northern (Sandy) trailhead: Take Wasatch Blvd to Hidden Valley Park, about two miles south of Little Cottonwood Canyon on the east side of the road. ( From I-15, take the 90th South exit, which will turn into 94th south as it approaches the mountains. At the mouth of Little Cottonwood, turn right on Wasatch.) The park is located on a curve in the road just past a large church on your left. From the parking area, bike towards the mountain on the paved path. After 100 yards, you should see a "Bonneville Shoreline Trail" sign pointing uphill. This connects via a steep doubletrack to the upper trail. For the lower connector, go further on the paved trail and turn left on singletrack after about 100 feet. (For a loop ride, the Hidden Valley singletrack is another 800 feet south on the paved trail.)
Bonneville Shoreline TH on Corner Canyon Road: 
From Draper, take 123rd South to 13th East and turn south (right). At the roundabout just down the hill, turn east (the equivalent of a left turn at the roundabout) on Pioneer Road. Go around one mile to 20th East, then turn right going south on Highland Drive. Turn left to the parking lot of Orson Smith Park, but immediately turn right as you enter the parking area. Drive on the gravel Corner Canyon Road 1.1 miles uphill. Turn right into the BST trailhead. Then northbound BST is on the uphill side of the road, across from the trailhead parking entry.
