Join us for the fourth London Calling, taking place once again in the capital of the United Kingdom. We look forward to inviting geocachers near and far to come along on 8th May 2027.
What can you expect from London Calling 2027? 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 going to a new venue.
Opening times on Saturday 8th May:
Platinum Pack purchasers: 10:30 AM to 4:00 PM.
General Entry: 11:00 AM to 4:00 PM.

Dates: 6th to 8th May 2027
Location: Greenwich Borough Hall, Royal Hill, London, SE10 8RE
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 (subject to change):
Thursday 6th May: 11:00 AM to 5:00 PM.
Friday 7th May: 10:00 AM to 5:00 PM.
Saturday 8th May: 10:00 AM to 4:00 PM.
Entry to the GPS Adventures Maze is free of charge, however, to prevent long queues on Saturday 8th May, we may be implementing a virtual queuing system. Details of this will be sent out as an announcement a week before the opening of the maze if necessary. This is purely so you can spend more of your day geocaching and less time standing in line. Entry on Thursday and Friday 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!
