What it is

Geocaching is another location based game where people locate physical items called "geocaches" or "caches" based upon GPS coordinates. It has a rather large user base and is played throughout the world. While there are several different websites that list geocaches, as of 2013 the most widely used one globally is geocaching.com.

How it relates to Geohashing

The Hash collision achievement is earned by stumbling across a geocache while at a geohash point. The reverse is also possible, with someone finding a geocache somewhere and realizing that they are close to a hash-point. Both games can involve visiting far-flung GPS coordinates.
