London Calling 2025 is coming!!!

Following two successful Mega events in 2021 and 2023, we are pleased to announce that will be returning once again in 2025. We will be at Central Hall Westminster, where we hosted London Calling 2021. Right in the heart of the city, opposite Westminster Abbey, on 3rd May 2025.

But this time we’re doing something extra special. We are bringing the GPS Maze back to the UK for only the second time. So keep your eyes on our social media channels and this website for updates over the coming months. Geocaching.com listings will go live at the start of May.

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.

London Calling 2025
Just in case people hadn’t realised… the earlier post about Dublin Calling was indeed an April Fools.That being said, if a bunch of Irish geocachers were considering it, and wanted to get in touch to ask about logistics and so forth, I think many Mega organising committees would be more than helpful to lend advice and support. London Calling included.I know we would love to go to Ireland for a Mega event, and celebrate 25 years of Geocaching in Europe. See MoreSee Less
