What is geocaching?

Geocaching is a real-world game of hide and seek treasures with GPS. The treasures are usually just notes where you sign to indicate that you found them… or treasures where the rule is “take what you want, leave something of similar value”.

How to play it? Simply create an account in Geocaching webpage and install the app.

As the video shows, playing is really easy, just look for a geocache online or on the phone… and go for it. You will be surprise how many are there out there.

For doctor Who fans… the NPL is the time keeper agency in UK… and the geocache was left by an user called TimeLord.
