Mount Woodson is located in Poway, California (located northeast of San Diego) and is one of the harder hikes to do in San Diego county. The 6.4 mile hike culminates at the halfway point of Potato Chip Rock. So called because it's a thin rock that juts out into the air. Despite the hundreds of people who stand on it each week, it doesn't seem in danger of breaking off anytime soon. This hike is pretty steep and I did it two weekends in a row while training for the Inca Trail hike in Peru. It was tough, but worth it for the gorgeous San Diego views. Go later in the day for less crowds, though wear plenty of sunscreen as the San Diego sun will be much harsher.
