Geocaches Types

Physical Geocaches

Geocaches where you need to find an actual container.

traditional Traditional Cache - a geocache container is found at the coordinates posted on the website.
multi Multi Cache - a geocache which involves two or more stages. The stages will all be listed along with info or numbers you need to identify. This will all lead you to a final location where you will find the geocache.
unknown Mystery/Puzzle Cache - a puzzle has to be worked out either at home or in the field in order to determine the final coordinates for the physical geocache - check out this page for some tips on how to solve puzzle caches. Challenge geocaches are also listed as this type, Challenge caches are at the posted coordinates but a challenge has to be completed before claiming it as a find.
letterbox Letterbox Hybrid (only on Geocaching.com) - Letterboxes can be either Traditional, Multi or Mystery geocaches, except they also contain a stamp for letterbox finders to record their visit. Letterboxing is a hobby that originated in Dartmoor.
wherigo Wherigo Cache (only on Geocaching.com) - for more info see Wherigo.com - these geocaches are game based where you follow a story or complete tasks in the Wherigo app. Completion of the game will reveal or take you to the geocache. A Wherigo-compatible GPS device or smart phone is required. Check out this article by *geocass* in Seeker 18 to find out more.
moving Moving Cache (only on Opencache.uk) - a Traditional Cache that moves after each visit. Each finder must hide the geocache somewhere new after finding it and publish its new coordinates.

Virtual Geocaches

These geocaches are about a location or information and do not have a physical container to find.

virtual Virtual Cache - a location to visit and usually a question to answer to prove your visit to the location. On Geocaching.com, usually the geocache owner must be emailed with the answers to the question or task set on the geocache description, whilst on Opencache.uk this answer can be entered as a Password to claim the find.
earth EarthCache (only on Geocaching.com) - similar to a Virtual Cache, in which the geocacher learns about a geological feature. Logging requirements usually include answering questions surrounding this geological feature. Again answers should be emailed to the EarthCache owner in order to claim the find. Find out more at The Geological Society of America and in our Seeker article 'EarthCaches: the Appliance of Science' by Terry Marsh.
webcam Webcam Cache - a webcam is found at the published coordinates; its image can be accessed online. You must grab a screenshot on your smartphone, of you in the webcam image and post it with your log in order to claim a find.
cyber Cyber Cache (only on Terracaching.com) - a certain challenge outlined on the geocache page must be fulfilled with a picture posted to claim the find.
labs Lab Cache (only on Geocaching.com) - a separate app where an Adventure Lab leads you around a collection of locations where you will be asked questions. Each question correctly answered will count as a geocache find.

Event Geocaches

event Event Cache - an event at a specific location with a specific time and date associated with it. Open to all to attend, with the shortest event lasting 30 minutes. These events have less than 500 attendees.

Geocache Sizes

Geocaches come in a range of shapes and sizes. To help when you are searching knowing the size could narrow down the possible locations the geocache could be hiding.

Geocache Sizes
micro Micro - the smallest geocache size and typically contain just a log sheet. Examples are a 35mm film pot or a magnetic nano geocache.
small Small - typically a small tupperware box, no larger than 1 litre in size. It will hold a log book and some small items (trackables or swaps).
regular Regular - a geocache larger than 1 litre in size. Typically larger tupperware boxes, or ammo cans. Best for swaps and trackables.
large Large - a huge geocache larger than an ammo can and often filled with swag items.
