From the entrance to Veterans Park, I rode-walked @1/10th mile south on Arroyo Rd & made a hard right at the No Parking Sign and onto a single track trail. I call it the North Arroyo Creek Trail. In a little less than a mile you'll reach the East Shore trail. Then hike the next 2.5 mi segment clockwise and down to the Lake and back. Study the map with due diligence happy trails
