About GeoKrety

GeoKrety (From Greek geo = ‘earth’, and Polish krety = ‘moles’) is a service similar to TravelBug(TM) or GeoLutins, aiming at tracking objects you leave in geocache containers. People move these registered objects (called GeoKrety) from cache to cache and register each move with this service. The trip of each GeoKret is then presented on a map.

GeoKrety are not a trade item, you do not have to put something in the cache to take a GeoKret, and you should not take something from a cache in trade for a GeoKret. If you should take something from a cache, you should make a trade, and you can place the GeoKret.

The service is absolutely free (contrary to TravelBug) and easy to use. A GeoKret can be anything, but in most cases it is a small puppet.

Please see (and edit, if necessary) the article about GeoKrety at Wikipedia.

How to pronounce GeoKrety? ;)

Make your own GeoKrety
  1. Have an account in service
  2. Register the GeoKret and note down the GeoKret Tracking Code (eg XF3ACS) generated by the system. This code is secret and only you and people who find this GeoKret should know it.
  3. Print a label with GeoKret's name, Tracking Code, Reference Number (e.g. GK003F) and owner on it. Attach this label to GeoKret (e.g. a puppet)

Then you have to:

  1. Put your GeoKret in a cache and register its location in the service
  2. Have fun watching the trip of your GeoKret!

But maybe in the future we will be able to do more. So enter the waypoint anyway.

How to log dropping to cache?

GC waypoints are not fully supported by GeoKrety (Licensee shall not remarket, resell, and/or redistribute the Data or any derived portion(s) of the Data in its digital form to any third party whatsoever… from waypoint license agreement ). However you can easily use GeoKrety with GC caches.

There are two options:

Acceptable geographic coordinate formats

You can enter lat/lon coordinates in different formats:

Reference Number and Tracking Code

Reference Number

e.g. GK003F

It is a public number that may be used to refer a GeoKret. It consists of 'GK' prefix and 4 digits in hexadecimal system. You can use it to search a specific GeoKret or to link to this GeoKret. It is visible to everyone.

Tracking Code

e.g. XF3ACS

It is a secret identification code which is required to post logs such as "Grab", "Drop" and others for a GeoKret. Only the owner and geocachers who found the GeoKret should know this code. It is not recommended to post it anywhere. Of course this code must be written on GeoKret's tag to allow finders to log it.

Altitude and country code

Thanks to SRTM and GTOPO30 elevation data and lat/lon to country code conversion (geonames), each trip point has assigned an altitude and country code (a flag). According to that data, the altitude profile is drawn. Above data and plots are updated every 10-15 minutes.

QR Code

For easy logging dropping or grabbing during your trip, I've added the possibility of attaching QR code on the GK label. QR Code is a kind of bar code, which can be "scanned" by your mobile phone, which will redirect you to the proper page at ; you will not have to enter the Tracking Code, everything will be encrypted in the QR. Read more about QR Code.

QR code of

The QR code with encrypted address of page.

When you find a GeoKret with QR code on the label you can:


  1. Take a photo of the code with your mobile phone
  2. Decode it and click on the url
  3. Log the grabbing or hiding the GeoKret. The Tracking Code will be indicated by the url.

How to decode?

You can use the free software for your mobile phone, eg: Barcode Scanner
