Let's get together for a hour of Camaraderie,
Geo-Talk and Geo-stories!

It’s incredible to think that one small action could chart a course toward something so big. On May 2, 2000, that’s exactly what happened as the pivotal decision was made to flip the “Blue Switch,” leading to geocaching as we know it today.
On May 2, 2000, the United States government decided to discontinue restricting GPS accuracy, known as Selective Availability, making GPS technology more accurate for everyone. May 2 became known to geocachers as “Blue Switch Day.” The first geocache was hidden the following day on May 3, 2000.
This first hide started a chain of events that no one could have predicted. This eventually resulted in the game of geocaching, a global hobby with over 3.3 million geocaches!

To celebrate 25 years of geocaching, there are two new souvenirs to earn for Blue Switch Day 2025!
Blue Switch Day 2025 finder:
- To earn this souvenir, geocachers must find and log one geocache, attend an Event, or complete an Adventure Lab® Location between May 2 and 4, 2025.
Blue Switch Day 2025 hider:
- To earn this souvenir, geocachers must have a non-Event geocache published between May 1 and 31, 2025.
- Any non-Event geocache type (excluding Adventure Lab) counts, as long as it is published between May 1 and May 31.
