If you have completed the first three caches of the East Lothian Quartet, you should have the full set of coordinates for the Bonus Cache.
Park at the given waypoints. These are the coordinates given above for this cache. The nearby beach has won awards for its clean water for paddling and bathing. There are great views across the Firth of Forth, with Fidra island and its lighthouse close by.
The cache is over a mile from the carpark, so allow plenty of time for the walk. You may wish to avoid times of the very highest point of the tide as it makes walking along the beach more difficult.
