Cargreen Quay
This, probably, is a simple Cache & Dash, if parking the car at Cargreen. Resident only private parking on the Quay, but there is usually on street parking available, with no yellow line restrictions. Alternatively check the parking Waypoint listed for Cache 7. Alternatively of course, it is possible to come ashore here at the Quay.Houses and boats are what might be called "fairly impressive" here.
Hide is one more Petling tube, ground level, just where you would hide it.
