I took the Seaborg Trail and hiked up to the Crescent Ridge Trail and back. For a total of 3.8 miles I finished in little more than an hour. Got some good workout with some fantastic sunset view on the way.

Longer loop that is less traveled than most of the trails on the Reliz Valley Rd side. A good cardio and a good place to put some miles on with less people
