London Calling 2025

London Calling 2025 is LAUNCHED!

We’re pleased to say that London Calling 2025 is now live – we’re taking place on 3rd May 2025, at Central Hall Westminster. That’s a return to the same location as London Calling 2021, right opposite Westminster Abbey in the heart of London, a short walk from Trafalgar Square and only moments from the Houses of Parliament and the Elizabeth Tower/Big Ben.

We are also currently the first and only Block Party listed in the United Kingdom, so we’re pleased to be bringing that icon to our country for the first time. Further news on the launch of the UK GPS Adventures Maze will be coming over the next month or two as we set that up for launch on

What is the significance of a Block Party, I hear you ask? It’s a special type of large scale geocaching event, which until now has only been hosted by Geocaching HQ at their base in Seattle. To celebrate 25 years of geocaching, they are allowed Block Parties to take place worldwide. In order to be a Block Party, the focus has to be on celebrating the history of Geocaching – something we’re taking to heart as this year’s theming is Geocaching’s birthday party!

London Calling 2025 Announcement

Behind the scenes, the London Calling Committee have feverously been working away on our plans to return for a third time as London Calling 2025. We’ve now got our venue confirmed, and so we can finally make some announcements that we’ve been eager to tell everyone about.

London Calling 2025 will take place on 3rd May 2025.

It will be hosted at Central Hall, Westminster. For attendees of LC21, this will be very familiar, as we’re going back to that venue. It’s a minute’s walk from Parliament Square, and directly opposite Westminster Abbey. The site is a brilliant location if you want to combine tourist activities in London with Geocaching.

The other major news is…. WE ARE BRINGING THE GPS MAZE BACK TO THE UK!!!!!

That’s right, for only the second time ever, the GPS Adventures Maze will be appearing in the UK, having previously appeared at the North Wales Mega in 2016. Except this time, it’s a debut of a brand new UK-specific maze, rather than one which has been borrowed from elsewhere.

The maze will be available to visit between 1st to 3rd May 2025, and will also be located at Westminster Central Hall. It will be free to access, and we will be publishing details of the virtual ticketing/queue system over the next few months. We’re aware that in some cases people have had to physically queue for several hours to get into the GPS Maze at certain events, and we’re keen to avoid that as much as we can.

The listing for both will go live at the start of May 2024, with ticket sales for the main event, supporters packs, coin sales etc, all going live at the same time.
