The third 2025 hiding theme: Hidden gems 💎

In 2025, we’re celebrating a major milestone—25 years of geocaching! To mark this special anniversary, we’re introducing a new hiding theme per quarter to celebrate geocaches published in 2025. Every three months, we’ll feature geocaches from the previous quarter’s theme on the Geocaching Blog and social media.

Our second theme, Back to nature, was incredibly exciting, showcasing some unique and creative geocaches in the great outdoors. We can’t wait to keep the spirit going by sharing some inspiration for next quarter’s hiding theme.
