I'd consider a shaded-in area with wiggly outlines, big enough to be path shaped, that just says "walk". That conveys "you need to get yourself to this pin, and we don't know how to help you".

Obviously, mapping a destination on an island with wiggly lines through the water which say "walk" would not be useful, but wasn't the situation I was envisioning.
