Geocache Description:

With the number of different challenge type caches being set we wanted to create something a little different.

To complete this challenge all you have to do is find a total of 134 different caches; how difficult can that be?

The cache is not at the published location which is the centre point of the playing area for this challenge.

What is the Explorer 134 Challenge?

The cache is called the Explorer 134 Challenge because each of the 134 different caches you need to have found to qualify must be in a different British Ordnance Survey grid square as depicted on the Explorer 134 Crawley & Horsham map.
The caches can be of any type, previous finds qualify (including those finds now archived and events attended (even if you were the host)), in fact just about any cache other than those you have placed yourself (more on that later) can be counted.
To find out more about this and other Explorer Challenge caches, go to which has been created to complement the cache series.

For the purposes of this challenge the published co-ordinates of all caches, including Unknown/Mystery and Multi caches are those that are to be used when determining which square a cache counts towards

To help those of you that want to plan your finds a GSAK Macro has been written which produces a web page of your finds, example output shown below. I hope to expand the GSAK Macro in the future to show caches that you have not found in the appropriate squares and include links to a well known street mapping website to show map tiles of areas you need to find a cache in.

When you have found the 134 caches you need to provide proof of that fact to be eligible to claim a find on the cache; this can be via one of any number of different methods you may have available:

  1. List the 134 cache codes and names in corresponding grid reference order in your found log
  2. Create a public bookmark list
  3. Add the GSAK Macro generated file to your profile page or upload the image with your log.
Any finds without proof of qualification will of course be deleted! Have fun!
