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.
