This is part of a 6 cache round based on the outer parts of the brown waymarked trail (Lochaber trail).
Each cache can be done as a stand-alone cache but also contains a clue for the coordinates of a bonus cache.
There is usually a pamphlet containing a route map available in the car park. This map can also be downloaded from several online sites including www.walkscotland.
You can walk eiher way around this delightful man-made lochan. Lots of places to view the wee beasties in the water and have a picnic at the sculpted table.
Perhaps now is the time to see if you can decrypt the coordinates for the bonus cache
