This Wherigo game (cartridge available here) will get you walking about as if you are lost before leading you to a physical geocache.
It should take less than an hour including a walk to the final location.
There are some randomised elements, so the game will change each time it's played. If there is more than one of you, why not each have a go.
The initial coordinates are for a "meeting of footpaths" where the Wherigo starts.
Please avoid spoilers in your logs. (If there is something that works or doesn't work or you like or dislike please send a message through my profile page.)
The cache contains a logbook (BYOP) and has room for small trackables and swaps. Please rehide it carefully as found.
