To get to there, start at the parking area at Black Road and Montevina Road. Follow the trail on the left side of the parking area and take the short walk down to the mini dock. From here, you can probably see where the cache is hidden. There are a lot of thorns and brush in this area, but there are pretty good trails that will take you to the cache area. You don't need to go bushwhacking, although the thorns are everywhere so I can't guarantee that you can avoid 100% of them. One area might be a little wet once it starts raining.
You're looking for a camouflaged piece of PVC pipe, bigger than a micro, but small enough that it holds tiny swag only. This should be an easy find for Highway 17 commuters!
