To those already in London the day before the Block Party, welcome to the weekend of London Calling 2025! We open the events just across the river between Lambeth North Tube Station and Elephant and Castle Tube Station at Notre Dame Roman Catholic Girls' School, which is right over the road from the Imperial War Museum. We will be in the main hall between 6:15 PM and 7:15 PM.

This is a chance to meet up with other cachers from near and far on the day before the Block Party. There won't be any food/drink available directly on site but there's a variety of coffee shops etc just a short walk away.

As we come together to celebrate the 25th birthday of Geocaching weekend, did you know that the Happy Birthday song actually has three verses? The second verse goes:

From good friends and true,
From old friends and new,
May good luck go with you,
And happiness too.
