Update 2025: Paddle and climb to get to the final for a true 5* terrain experience. This route avoids private property. Note that this approach has hazards that need to be managed with suitable equipment and skills.
To find th' location 'o th' penultimate waypoint ye need to find a path through th' ocean grid below. Th' path shall pass through all but 10 accursed squares, shall not cross itself 'n be continuous. 'tis only to be sailed by main 4 compass points and 'tis gunna guide thee to a cairn atop a large boulder 'n th' coordinates fer th' final cache. Th' final booty be nearby but high above ye head.

When you have the solution please check for more notes here by checking your coordinates.
