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!
