This was London Calling 2025
Thank you all once again for attending another successful London Calling event, this time as the UK’s first ever Block Party. We had around a thousand people attend the main location at Westminster. Nearly that many went to Brentford for the return of the GPS Adventures Maze, and the debut of the first custom-built version for the United Kingdom.
London Calling 2021 (GC8JAYF) was the city’s first Geocaching Mega Event. It took place on 28 August 2021, at Central Hall Westminster. Cachers from all over the UK and around the world attended, with the event becoming the largest Geocaching event ever to take place in the city.
London Calling 2023 (GC9MAXX) took place on 29th April 2023 at St Mary’s Church, Marylebone. Attendance was nearly double that of LC21, with visitors coming in from as far afield as Singapore and Australia, making us the world’s fifth-biggest geocaching event of 2023 and the third-biggest event ever to take place in the UK.
For London Calling 2025 (GCAK7KC), we returned to Central Hall Westminster on 3rd May 2025 for the UK’s first Block Party event. This event celebrated 25 years of Geocaching and was part of the busiest mega day ever, with seven events taking place around the world that day. It also saw the return of the GPS Adventures Maze to this country for the first time since 2016, and the debut of the first purpose-built Maze for the UK.
