Join the global trend and get the kids outdoors for some GPS treasure hunting this winter…

geocache hidden

Calling itself ‘the world’s largest treasure hunt’ geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices.

The words ‘outdoor’ and ‘treasure hunting’, go some way to explaining why the pursuit has caught on all over the world, with some 2.5 million ‘caches’ hidden around the globe, in over 100 countries, and on all seven continents, including Antarctica.

Above all geocaching is a fantastic way of coaxing the whole family into the outdoors and discovering wild spots all around the country and even right on your doorstep, which you might never have known existed.

The principle is simple: a geocacher will hide a small waterproof container, such as a 35mm film canister, somewhere in a usually wild public space, and then post the GPS coordinates of the cache on the internet for other geocachers to hunt and find. Caches are grouped by type and difficulty and come with Typically the cache contains a logbook for the finder to sign and date, and often an exchangeable treasure, such as a coin or small toy for them to take, leaving something else in its place for the next finder.

Some might be put off by the mere mention of ‘GPS devices’ but in reality this means that you can take part with pretty much any smartphone, almost all of which have built-in GPS capability. If you have mobile data, even better, as you can use Google Maps to display and hunt caches directly from the geocaching apps for both Android and iOS devices.

Not having a GPS or smartphone makes geocaching less convenient but certainly not impossible: create an account on one of the sites, and print off maps and clues from there. Even better, mark a few sites on an OS map, take a compass and practice some family navigation skills!
