East Mountain Wilderness Park Kaysville
On Rte 89 bewteen mile markers 38 and 40 in Fruit Heights, turn east onto 400 N. Immediately turn left (north). Follow this road for 0.6 miles. You will come to a dirt parking area with a huge sign for "East Mountain Wilderness Park Kaysville".
You can access the Bonneville shoreline trail here heading north. It is also possible to continue up the paved road to another parking area to hit the Bonneville trail heading south. However, the trail does not go very long before stopping. Since it is rocky, I don't advise the southerly direction for biking.
