In 2025, we’re celebrating a major milestone—25 years of geocaching! To mark this special anniversary, we introduced a new hiding theme per quarter to celebrate geocaches published in 2025. Every three months, we feature geocaches from the previous quarter’s theme on the Geocaching Blog and social media.
Our third theme, hidden gems, was a shining success! We loved seeing all the ways you, the community, interpreted the theme. All nominations were polished to perfection, and we are excited to keep the spirit going by sharing some inspiration for the last hiding theme.
