So I've found a few of these doing trail maintenance and forestry in the rockies on accident, and I remember hearing about them when I was a kid, but how are you supposed to find these things?
There's a website, geocaching.com -- it's free to make an account, and there is a world map showing where geocaches are hidden.
The easiest type (traditional caches) will just have a location on the map where you go to find the container. Some of the more difficult ones, you might have to solve a puzzle before you can find out where you need to go looking
Fascinating, I wonder if the one's I've found before are on there, they were in an area that, while not closed to the public, I've never seen in 3 years of arbory anyone there that wasn't there with me. Deep woods in-between ski trails.
EDIT: Well, the map pulled up nothing anywhere near this town, so I wonder how else people are finding them.
Yup, geocaching has definitely taken me pretty far off the beaten path in the past.
Entirely possible that there are premium geocaches in that area, which you'd have to pay to see. Or it could also be puzzle caches, which would show up in a different (but likely close by) spot on the map
