What is a challenge cache?

A challenge cache requires seekers to find an associated physical cache, and to find an additional set of geocaches as defined by the challenge owner. Challenge caches encourage geocachers to set and achieve fun goals.

What are digital Treasures?

Treasures are digital items grouped into collections, often organized around a theme. Geocaching HQ introduced the Treasures feature to celebrate 25 years of Geocaching. The fifth collection is titled Mystery Books and released in May 2025. It features finding non-traditional caches with a difficulty rating of 2 or above! smiley
