"Likely the most popular hiking destination within the city, Cowles Mountain is the highest peak in San Diego. If you want a tranquil, nature-filled hike, look elsewhere. For all of its merits, the trail is shared with dozens of other hikers and runners; the secret is out. But if you're looking for a stellar Instagram op or view though, it's worth the 30-minute drive from downtown and the crowd navigation." - Archana Ram
