Join us for the third London Calling, taking place once again in the capital of the United Kingdom. We look forward to inviting cachers near and far to come along to the very special 25th birthday party in honour of Geocaching’s 25th birthday on 3rd May 2025.
What can you expect from London Calling 2025? More of the same fun and laughs we’ve had in previous years. Crazy lab caches (who remembers playing the violin last time?), and we’re returning to an incredible venue at Central Halls Westminster. The location is directly opposite Westminster Abbey, in the heart of the city, and a mere minute’s walk from Parliament Square.
Opening times on Saturday 3rd May:
Platinum Pack purchasers: 10:30 AM to 5:00 PM.
General Entry: 11:00 AM to 5:00 PM.

Dates: 2nd to 4th May 2025
Location: British Suzuki Music Association, Brentford
What is the GPS Adventures Maze? It is an exhibition where you can learn all about the development of GPS, and about both the history of geocaching worldwide and specific to the United Kingdom. It will take you through a variety of concepts related to geocaching local to the UK, and feature a series of adventure lab caches to test your knowledge throughout.
Due to size constraints, it will not be possible to provide full-size translated panels in multiple languages, but the panels have been designed with smartphone translation services in mind and translations of the panel texts will be available online with links to those pages available via QR codes locally.
Opening times:
Friday 2nd May: 10:00 AM to 5:00 PM.
Saturday 3rd May: 10:00 AM to 4:00 PM.
Sunday 4th May: 10:00 AM to 5:00 PM.
Entry to the GPS Adventures Maze is free of charge, however, to prevent long queues on Saturday 3rd May, we will be implementing a virtual queuing system. Details of this will be sent out as an announcement a week before the opening of the maze. This is purely so you can spend more of your day geocaching and less time standing in line. Entry on Friday and Sunday will be first come first served, however, we reserve to right to use the virtual queuing system on those days if we find that people are waiting a long time for entry. Although queues are very much a British thing, we’d still very much rather you didn’t have to do it!
We are also having a launch event on the morning of Friday 2nd May from 9:30 AM to 10:00 AM. The GC code and link for this is: GCAM2ZD.
