Imagine if movies like Indiana Jones or National Treasure turned into real-world adventures. Geocaching is an outdoor treasure hunting game that uses GPS coordinates to locate a hidden geocache (container). Millions can be found all over the world, and many are hidden in story-worthy locations (think hidden temple in Cambodia). Caches come in different shapes and sizes and include trinkets from its place of origin. Once found, you are encouraged to sign a log, take the treasure inside and replace it with a new one.

Liz and Josh are the authors and founders of the travel blog, Peanuts or Pretzels, based out of Atlanta, Ga., and are experts on geocaching. According to their blog, their first geocaching experience was during a trip to Gatlinburg, Tenn. A couple of months later, they were off to Europe and used geocaching as another way to explore the countryside and cities in Scotland and Ireland.

There are more than 10 million registered users on and more than 2.5 million hidden caches in 180 countries. Geocache listings include difficulty and terrain ratings (1 being the easiest and 5 being the most difficult) to help you chose an adventure that is right for you.

In their blog, Liz and Josh list the top reasons to go geocaching. Aside from experience and adventure, geocaching is budget-friendly and can be done by downloading a free app on your smart phone. Just choose the cache you want to find and navigate to its location. It’s also educational and gives you a unique opportunity to learn about a destination, whether it is through history, landscapes or culture.
