Letterbox Hybrid

Cache In Trash Out is the environmental initiative supported by the geocaching community. The main aim of this program is to clean up natural areas that we enjoy while geocaching. These events are gatherings of geocachers that can focus on litter clean-up, removal of invasive species, planting trees and vegetation or trail building. Often CITO organisers are able to get local council support for the clean up.


This type of geocache will usually involve puzzles that need to solved at home or in the field to determine the correct coordinates. The mystery/puzzle symbol is also used for challenge caches. Challenge caches involve the seeker to have meet a certain criteria before the found log can be made.  Mystery/Puzzle Caches often become the staging ground for new and unique geocaches that do not fit in another category.

These geocaches involve visiting two or more locations, with the final location being a physical container with a logbook inside. There are many variations, but typically once you’re at the first stage, usually the listed coordinates, you will receive a clue to the whereabouts of the next stage. The second stage will have a clue for the third, and so on. The whole cache process from stage one to the final can be spread over a few metres or over a  number  of miles.

The origin of Letterboxing can be traced to Dartmoor, Devon, England in 1854. Letterboxing is another form of treasure hunting that uses clues instead of coordinates. These days some letterbox owners make their container both a letterbox and a hybrid type of geocache and post its coordinates on Geocaching.com. These types of geocaches will contain a stamp that is meant to remain in the box and is used by letterboxers to record their visit.


Event Cache

Wherigo is a toolset for creating and playing GPS-enabled adventures in the real world. A Wherigo-enabled GPS device or an app on your smartphone is required to play a Wherigo. By integrating a Wherigo experience, called a cartridge, with finding a geocache, the hunt can be a great adventure. Among other uses, Wherigo allows geocachers to interact with physical and virtual elements such as objects, sounds or characters.

An Event Cache is a social gathering of local geocachers or geocaching organizations. The Event Cache page specifies a time for the event and provides coordinates to its location. Events can be pub meal, quiz nights, introduce new players to geocaching or small meet to sit around and have a chat with like minded folk.

For the lastest Scottish events check out our events page.

A Mega event is just like Event Caches, but they are attended by 500+ people. Many of these larger events offer geocachers a day (or days) of planned activities. There are often several days of additional activities surrounding a Mega-Event. These large events attract geocachers from all over the world and can be held annually.  The UK has an annual roaming MEGA, with 2018 planned for Yorkshire. 2018 also see's the Piratemania return. Show both these events your support and log a 'Will Attend'.

A geocache type that is no longer available for creation, but can still be found, webcam geocaches use existing web cameras. The idea is to get yourself in front of the camera and save a screen capture from the website where the camera is displayed in order to log a find. Sadly only two remain in Scotland, one in Edinburgh and the other in the Cairngorms National Park.

This is the original type of geocache and the most straightforward. These geocaches will be a container at the given coordinates. The size of the cache may vary, but at minimum, all of these geocaches will have a logbook, which must be signed. Larger containers may hold items of swag available for trade and trackables or geocoins. The first traditional cache placed in the UK was published in Scotland. "Scotland's First"

Mystery or Puzzle Cache

Virtual Cache


EarthCaches are a type of virtual cache where seekers visit locations based on special geological features. The object of an EarthCache is to learn something about our planet. EarthCache pages include a set of educational notes along with coordinates. An Earhcache is placed to present a lesson on the geology of a location. It could be how that place formed, about why that place is important scientifically or what that site can tell us about our planet’s geology. more information can be found at http://www.earthcache.org/

A Virtual Cache is about discovering a location rather than a container. This geocache type that is no longer available for creation, but can still be found. The requirements for logging a Virtual Cache can vary. You may be required to email an answer a question about the location, take a picture or complete a task. You must visit the coordinates before you can post your log. Scotland still has 28 virtual caches with the most favourited in South Ayrshire.
