I went for a hike in Fallbrook along the Santa Margarita River Trail. The river is really nice. All of the many varieties of trees, giant granite boulders, river endlessly dropping into large pools, What more could you ask for. I can tell a lot of people walk this trail so don't expect to be alone in this part of the wilderness. Its beautiful out there though and a great place to take the kids. I plan on going again soon.
