Geocaches can be found by using a variety of listing sites. The most popular listing site in the UK is geocaching.com, but there are others too opencache.uk and terraching.com. The GAGB does not affiliate itself with, or promote, any of these major listing sites over the other.
Geocaching.com is the largest geocache listing site with millions of geocaches. Many are available to free members, while upgrading to premium allows access to all geocaches and many features to assist in your searches.
Opencache.uk is a smaller site with only a thousand geocaches, where all of their geocaches listed are available to all members for free. The Opencache UK site forms part of a global network of Opencaching sites.
Terraching.com is a sponsor enrolment site where two other geocachers in the Terracaching community sponsor your membership. It has the least number of geocaches in the UK with only a few hundred geocaches but thousands can be completed anywhere.
