If you want to get some serious rays while working out, there’s no better hike in the East Bay than the Stonewall-Panoramic Trail in Claremont Canyon Regional Preserve in the Berkeley hills. The trail also offers some of the best views in the Bay Area. If you want to warm up your calves and quads before taking on the super-steep parts of the hike, start off at Willard Park in Berkeley and head east up Derby Street toward the hills. You’ll then connect to the trail via a staircase at the intersection of Derby and Tanglewood Road. Within minutes, your heart will be pumping as you begin your ascent. First, you’ll hike through a towering eucalyptus grove before coming upon the first of a series of lookouts that provide sweeping views of San Francisco Bay. Then the steep part of the trail begins as you head up to the top of Panoramic Way. But don’t stop there — keep going and connect to the East-West Trail on UC Berkeley property. And don’t forget water or sunscreen.
