London Calling 2025

What is a Block Party exactly?

Many of you will know that London Calling 2025 will be hosting a Block Party at Westminster Hall, instead of the usual Mega, that we held in 2021 and in 2023. However, some people are unaware of what a Block Party is and have asked for an explanation.

HQ hosted the original Block Parties in Seattle from 2011 to 2015. Only 5,064 geocachers received the Block Party icon during those years, which goes to show that it was a fairly exclusive activity. Geocaching HQ have offered the international geocaching community to host Block Parties to allow more people to earn this rare icon on their profile.

A Block Party is still an event, similar to a Mega, and needs to abide by the following criteria:

• Take place between January 1, 2025 and December 31, 2025.

• Qualify as a Mega-Event or Giga-Event.

• Have at least 300 Will Attends.

• Be at least 6 hours long.

• Highlight celebrating 25 years of geocaching.

On May 2nd 2000, GPS was made public; on May 3rd 2000, the first geocache was placed and the game was born. 2025 is the year to celebrate 25 years of Geocaching and London Calling’s Block Party falls on the very same weekend as the 25th anniversary of the first geocache being placed.

Inside Westminster Hall, you will find many fun and interesting stalls, including geocoins, trackables, merchandise, a creatively designed log book and physical Adventure Labs. If you haven’t done so already, please post your Will Attend as this will really help with our planning and organisation to make the event as enjoyable as possible for everyone involved.
