There are caches hidden on 5 different public shorelines on Bainbridge Island. To get the complete coordinates for each cache (the listed coordinates are for a spot nearby), you must correctly answer two multiple choice questions relating to Puget Sound shorelines.
A few caveats:
Wear good walking shoes suitable for beaches and possibly muddy trails.
This cache requires a walk of about 1/4 mile down and back up a fairly steep trail that can get muddy in places after a rainfall.
This is a Cache In, Trash Out geocache quest! So instead of replacing the prize with your own gift, help yourself to one of the plastic trash bags in the cache and use it to pick up any litter you may find on the beach or trail. Thanks!
