This series will be difficult. There is a lot of bushwhacking to get to some of the locations, though if you take the time to really study the satellite view of the map you will be able to find trails that will get you reasonably close to the containers. (After bushwhacking 400+ feet through thick head-high brush including manzanita to get to number 5, I pushed through the brush onto a trail that is right next to where the cache needed to go. In looking later at the satellite view there were two trails that were a longer distance between caches, but avoided almost all of the bushwhacking).
Best parking is at the west end of Jupiter Ave off of Constellation Rd. Then start the series with Number 19 and work your way around the circle.
This series is within the boundaries of the Burton Mesa Ecological Reserve on the south side of Highway One. Bordered on the south by the Lompoc Federal Penitentiary and to the west by Vandenberg Air Force Base.
