This is the original geocache type consisting of, at minimum, a container and a
log book or logsheet. Larger containers generally include items for trade. “Nano”
or “micro” caches are tiny containers that only hold a logsheet. The coordinates
listed on the traditional cache page provide the geocache’s exact location.
Multi-Cache (Offset Cache)
A Multi-Cache ("multiple") involves two or more locations. The final location is
a physical container. There are many variations, but most Multi-Caches have a hint
to find the second cache, and the second cache has a hint to the third, and so on.
An offset cache (where you go to a location and get hints to the actual cache) is
considered a Multi-Cache.
Project A.P.E. Cache
In 2001, fourteen geocaches were placed in conjunction with 20th Century Fox to
support the movie Planet of the Apes. Each cache represented a fictional story in
which scientists revealed an Alternative Primate Evolution. These caches were made
using specially marked ammo containers. Each cache had an original prop from the
movie. Only one Project A.P.E. cache still exists today.
Mystery or Puzzle Caches
The "catch-all" of cache types, this form of geocache may involve complicated puzzles
that you will first need to solve to determine the coordinates. Mystery/Puzzle Caches
often become the staging ground for new and unique geocaches that do not fit in
Letterboxing is another form of treasure hunting using clues instead of coordinates.
In some cases, the letterbox owner has made their container both a letterbox and
a geocache and posted its coordinates on Geocaching.com. If there is a stamp inside
a Letterbox Hybrid, it is not an item intended for trade; the stamp is meant to
remain in the box so that visitors can use it to record their visit. To read more
about letterboxing, visit the Letterboxing North America web site.
Wherigo is a toolset for creating and playing GPS-enabled adventures in the real
world. By integrating a Wherigo experience, called a cartridge, with finding a cache,
the geocaching hunt can be an even richer experience. Among other uses, Wherigo
allows geocachers to interact with physical and virtual elements such as objects
or characters while still finding a physical geocache container. A Wherigo-enabled
GPS device is required to play a cartridge. Learn more at Wherigo.com.
An Event Cache is a gathering of local geocachers or geocaching organizations to
discuss geocaching. The Event Cache page specifies a time for the event and provides
coordinates to its location. After the event, the cache is archived.
A Mega-Event cache is an Event Cache that is attended by 500+ people. Mega-Events
offer geocachers a day 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 are often held annually.
Cache In Trash Out Event
Cache In Trash
Out is an activity intimately tied to geocaching. While searching for caches,
geocachers collect litter along the trails and properly dispose of it. Cache In
Trash Out Events are larger gatherings of geocachers that focus on litter clean-up,
removal of invasive species, revegetation efforts or trail building.
An EarthCache is a special place that people can visit to learn about a unique geoscience
feature of our Earth. EarthCache pages include a set of educational notes along
with cache coordinates. Visitors to EarthCaches can see how our planet has been
shaped by geological processes, how we manage its resources and how scientists gather
evidence to learn about the Earth. For more information about EarthCaches, visit
Groundspeak Headquarters Cache
Headquarters Cache is located at Groundspeak HQ in Seattle, WA. Geocachers
interested in visiting HQ to log the cache should send an email to firstname.lastname@example.org.
GPS Adventures Maze Exhibit
A GPS Adventures Maze Cache represents attendance at the GPS Adventures Maze Exhibit
or a regional variation of this Exhibit. GPS Adventures Mazes are designed to teach
people of all ages about GPS technology and geocaching through interactive science
These are cache types that are no longer available for creation on geocaching.com.
Waymarking web site for other GPS hunting activities.
A Virtual Cache is about discovering a location rather than a container. The requirements
for logging a Virtual Cache vary—you may be required to answer a question about
the location, take a picture, complete a task, etc. In any case, you must visit
the coordinates before you can post your log.
Although many locations are interesting, a Virtual Cache should be out of the ordinary
enough to warrant logging a visit.
Virtuals are now considered waymarks on Waymarking.com.
These are caches that use existing web cameras placed by individuals or agencies
that monitor various areas like parks or business complexes. The idea is to get
yourself in front of the camera to log your visit. The challenging part is that
you need to call a friend to look up the web site that displays the camera shot.
You will need to have them to save the picture in order to log the cache. If you’re
a tech-head you could save the image yourself by using a wireless modem and a laptop.
Webcam caches are now in the Web Camera category
10 Years! Event Cache
A 10 Years! Event Cache is a special Event Cache type for events held April 30 -
May 3, 2010 to celebrate 10 years of geocaching.
Locationless (Reverse) Cache
A Locationless Cache could be considered the opposite of a Traditional Cache. Instead
of finding a hidden container, you locate a specific object and log its coordinates.
Locationless caches have evolved into Waymarking.
