London Calling 2025 is coming!!!

Following two successful Mega events in 2021 and 2023, we are pleased to announce that we are returning for London Calling 2025 (GCAK7KC)! We are at Central Hall Westminster, where we hosted London Calling 2021. Right in the heart of the city, opposite Westminster Abbey, on 3rd May 2025. This is going to be the first ever Block Party in the UK!

But this time we’re doing something extra special. We are bringing the GPS Adventures Maze back to the UK for only the second time. Geocaching.com listings are now live for all our events, including the GPS Adventures Maze!

London Calling 2021 (GC8JAYF) was the city’s first Geocaching Mega Event. It took place on 28 August 2021, at Methodist 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.
