About International Geocaching Day
International Geocaching Day is an annual celebration of the worldwide GPS treasure-hunting game, held on the third Saturday of August. In 2026 it falls on Saturday, 15 August. Organised by Geocaching HQ (Groundspeak), the day encourages players, known as geocachers, to head outdoors, find hidden containers using satellite coordinates, and connect with a global community of millions.
How to Celebrate International Geocaching Day
The whole point of the day is to get outside and play, so the best way to mark it is to grab a GPS device or your phone and start searching. Here are eight ways to take part:
- Download the official Geocaching app – The free app from Geocaching.com turns your smartphone into a GPS receiver and shows nearby caches on a live map. It is the quickest way for a complete beginner to find their first cache.
- Find your first cache – Pick an easy one with a low difficulty and terrain rating, follow the coordinates, sign the logbook, and put the container back exactly where you found it. There is a good chance one is hidden within walking distance of your home.
- Earn the souvenir – Log a find or attend an event on the day and you will unlock a special International Geocaching Day digital souvenir on your profile. Collectors plan whole outings around bagging it.
- Attend or host an event cache – Geocachers organise meet-ups, picnics, and group hunts around the date. Search the map for an Event Cache near you, or create your own and invite friends and family along.
- Tackle a tricky hide – Challenge yourself with a high-difficulty cache, a clever camouflaged container, or one in an unusual spot such as a tree, a wall cavity, or under a fake rock.
- Try an Adventure Lab – Adventure Labs guide you through a location-based series of stops and questions, a great option for exploring a town centre or a park you have never visited.
- Move a trackable along – Trackables are tagged items with their own goals, such as travelling to a particular country. Pick one up from a cache and help it on its journey.
- Introduce someone new – Take a child, friend, or colleague on their first hunt. The thrill of spotting a hidden cache is the surest way to turn a newcomer into a regular player.
What is International Geocaching Day?
International Geocaching Day celebrates geocaching, a real-world outdoor game in which participants use GPS coordinates to locate hidden containers called caches. A typical cache is a small waterproof box holding a logbook, and sometimes a pencil and small trinkets to swap. Players navigate to the listed coordinates, sign the log to prove the find, and return the container for the next person. The day is run by Geocaching HQ, the Seattle-based company also known as Groundspeak, which operates Geocaching.com, the largest listing service for the game.

The History of International Geocaching Day
Geocaching itself began in May 2000, days after the United States government switched off Selective Availability, the deliberate degrading of civilian GPS signals. The improved accuracy made the game possible almost overnight. Dave Ulmer hid the very first cache, a bucket of items, near Beavercreek, Oregon, and posted its coordinates online. The hobby grew rapidly once Geocaching.com launched later that year.
International Geocaching Day arrived more than a decade later. The first one was held on 20 August 2011, originally conceived as another way to celebrate the Geocaching Block Party that Geocaching HQ was hosting at its Seattle headquarters. The idea caught on, and what began as a one-off tie-in became a fixed annual tradition on the third Saturday of August.
Since then the day has grown into a global occasion, with souvenirs awarded for finds logged on the date and thousands of community events held around the world. The game marked its 25th anniversary in 2025, with International Geocaching Day remaining one of the busiest dates on the geocaching calendar.
Fun Facts About International Geocaching Day
- There are more than 3.4 million active geocaches hidden worldwide, waiting to be found.
- Caches have been placed in 191 different countries and on all seven continents, including Antarctica.
- More than 1.2 billion “Found it” and “Event Attended” logs have been recorded since the game began in 2000.
- Every cache has a unique GC code (in the format GCXXXX) used to identify it in the global database.
- The first International Geocaching Day in 2011 grew out of the inaugural Geocaching Block Party in Seattle.
- Some caches sit at the bottom of lakes, up cliff faces, or in remote wilderness, requiring serious skill to reach.
Why International Geocaching Day Matters
Beyond the fun of the hunt, the day gets people outdoors, active, and exploring places they might otherwise overlook, from local parks to historic landmarks. It brings together a friendly worldwide community across all ages and backgrounds, and it shows how a simple idea built on free technology can turn the whole planet into a playground. If you enjoy getting outside, you might also like National Hike With A Geek Day, which pairs walking with shared curiosity.
