The North Wind Doth Blow
This is NOT a good candidate for a park-and-grab since there is No Parking in the area of the cache or trailhead!
NOTE: There is now a "No Trespassing" sign just a few feet before you reach the turn onto the trail. No idea what that is about, since this is still a very heavily-used trail.
Update March, 2022: Hikers on the trail beyond the "No Trespassing" sign informed me that this is considered a "local's only" trail and that local hikers visit often, despite the sign. If you are uncomfortable with the situation, consider hiking the loop in reverse, or doing the out-and-back from the Port Drive trailhead.
This is the first cache on a fantastic loop hike, and not far from the trailhead. See Citadel of the Sea for full details.
