Geocaching is essentially a high tech treasure hunt. Those of us who play use hints and information to lead us to the right location. Not exactly “X marks the spot”, but close enough. One type of puzzle cache takes this a step further and turns finding the right coordinates into a hunt of it’s own. This treasure hunt could take place in the real world or on a screen. The information you’re searching for varies greatly, sometimes you’ll be told to go and find something that’s at a specific location, sometimes you’ll need to get your Google on to search out trivia or historical information and other times you might need to search for information within the geocaching platform itself. Either way, you will need to collect information and answer questions to get the final answer. As long as you know what information you’re looking for, this type of puzzle cache is normally not too difficult to solve, it just requires patience to seek the answers and care to make sure they’re correct.
Some examples of caches that use this skill are: the Anniversary of Geocaching series by steve4nlanguage (GC5Z0DA, GC6PYKA, GC7ARAH), Xian Gong Miao Trail by rudychung (GC6VXR6) and Little Silver by monkey_travels (GC6R003).

One of the easiest types of mystery caches to solve is the bonus cache. To grab these, you often only have to collect information (usually parts of coordinates) from other specified caches. This cache is in the bag as long as you've already found GC7EP8J and GC7ENWG.
