Please do not park on the drive. As the parking waypoint says, the parking for one car is on the west side of the lane (opposite the drive entrance).
Which way will you go? This way or that? At the given coordinates you will find a small tube container with the coordinates of "This" and "That" in. Go to both of these for more small tubes. In each of these tubes will be one half of the coordinates to find the final cache which is somewhere between "This" and "That". Question is, which way will you go first? This way or that?
This cache has 4 stages, the given coordinates, with the coordinates inside of two other caches, "This" and "That". The fourth and final cache can be found by putting together the two halves, found in "This" and "That". The final cache is a container large enough for most trackables.
For those locally in the know, this is not affected by the roadworks for the new road going round the north of Lancaster.
