This global phenomenon encourages exploration, problem-solving, and camaraderie, providing a fun and engaging activity that combines the excitement of a scavenger hunt with the satisfaction of finding a hidden treasure. So, strap on your hiking boots, grab your GPS device, and get ready to embark on a journey of discovery as we delve into the fascinating world of geocaching.

The Motivator

Although I had come across snippets of information about the hobby online, I didn’t pay much attention to it initially. However, my close friend Charles, who got into geocaching a few years ago, has a knack for persuasion. His social media posts about his geocaching adventures are always enticing and have sparked my curiosity about the hobby.

Charles maintains a Facebook page dedicated to geocaching, where he not only documents his search for caches but also shares details about the ones he has hidden. In addition, he runs a website where he delves deeper into the world of geocaching, accompanied by a blog that highlights various aspects of the hobby. If geocaching piques your interest, I highly recommend visiting Public Land Fun. The website offers valuable insights for both novices and seasoned geocachers.

What is Geocaching?

Geocaching is an outdoor recreational activity where participants use GPS devices or smartphone apps to locate hidden containers, called geocaches, by following a set of coordinates. These geocaches are typically small waterproof containers with a logbook inside, where finders can sign their names and leave a short message. Some geocaches also contain small trinkets or toys that can be taken or exchanged, as long as the finder replaces it with another item of equal or greater value.

The concept of geocaching was born in May 2000, when the U.S. government removed selective availability restrictions on GPS technology, making it more accurate and accessible for civilian use. Shortly after, the first geocache was hidden by Dave Ulmer, marking the beginning of this exciting outdoor pursuit.

Today, geocaching has grown into a worldwide phenomenon, with millions of geocaches hidden in almost every country. The activity promotes exploration, adventure, and a sense of community among participants, who often share their experiences and discoveries with others through online platforms and social media. This is one of Charles’s finds.

Know your sizes

Geocaches come in various sizes, each offering a different experience for the geocacher. Understanding these sizes can help participants know what to expect when searching for a cache and what type of container they might be looking for. Here are the most common geocache sizes:

  • Micro: Micro caches are the smallest and can be as tiny as a fingertip. They often contain just a log sheet or a logbook, due to their limited space. Common examples of micro caches include magnetic key holders, film canisters, or small tubes.
  • Small: Small geocaches are larger than micros and usually have enough space for small trinkets, toys, or geocoins, in addition to a logbook. They are often containers like small plastic boxes or lock-and-lock containers, with sizes ranging from about 100ml to 1 liter.
  • Regular: Regular geocaches are the traditional size and can hold a variety of items, including small toys, trackable items, and more. These caches usually come in the form of plastic containers or metal ammo cans, with sizes ranging from 1 to 20 liters.
  • Large: Large geocaches offer the most space for a wide array of items and can be found in containers like large plastic bins, wooden boxes, or even repurposed household items. These caches may be more challenging to hide due to their size, but they offer a rewarding experience when discovered.
  • Other: Sometimes, geocachers may encounter caches that don’t fit into the standard size categories. These can include nano caches, which are even smaller than micros, or uniquely shaped containers designed to blend in with their surroundings.

Knowing the size of the geocache you are searching for can help you better focus your search and manage your expectations, making the experience more enjoyable and exciting.

A cache can be smaller than a pill bottle or big as a truck.

How to get started

Getting started with geocaching is easy and requires just a few simple steps. Follow these guidelines to embark on your first geocaching adventure:

  • Create an account: Sign up for a free account on the official Geocaching website ( or download the Geocaching app, available for both iOS and Android devices. There are also other geocaching apps available that you can explore.
  • Obtain a GPS device or smartphone: A GPS-enabled device, such as a handheld GPS receiver or a smartphone with GPS capabilities, is essential for locating geocaches. Many geocaching apps are available for smartphones, making it easier than ever to get started.
  • Search for geocaches near you: Once you’re logged in, use the search function on the website or app to find geocaches close to your current location or a specific area you’re interested in exploring. The results will display a list of nearby geocaches, including their coordinates, difficulty, and terrain ratings.
  • Choose a geocache and note the details: Pick a geocache that interests you and take note of the cache size, difficulty, and terrain ratings to ensure it’s suitable for your skill level and desired adventure. Read the cache description and any additional hints provided by the cache owner.
  • Navigate to the geocache: Using your GPS device or smartphone, input the coordinates of the geocache and follow the directions to its location. Keep in mind that the coordinates will guide you to the general vicinity of the cache, but you’ll still need to search for the actual container.
  • Search and find the geocache: Once you’re close to the location, use your intuition and geocaching skills to locate the hidden container. This may require some patience, creativity, and a keen eye for detail.
  • Sign the logbook and exchange items (optional): When you find the geocache, open it and sign the logbook with your geocaching username and the date. If the cache contains tradeable items, you can take one, but remember to leave an item of equal or greater value in return.
  • Log your find online: After you’ve found the geocache and returned it to its hiding spot, log your find on the Geocaching website or app. Share your experience, including any photos or anecdotes from your adventure, to contribute to the geocaching community.
  • Continue the adventure: Now that you’ve completed your first geocache, you can search for more caches, explore new locations, and even hide your own geocaches for others to find.

Remember to always follow the geocaching guidelines, respect the environment, and practice “Cache In, Trash Out” by picking up litter you encounter while searching for caches.
