A term used in Geocaching which refers to a geocacher making a trail where there isn't, or shouldn't be one. This action is frowned upon by the majority of the Geocaching community. Geotrails are usually the result of a poorly thought-out hide location for a cache.
In rare circumstances geotrails are useful, such as in a park that isn't able to maintain the trails due to budget cuts. In this case, a geotrail can be helpful.
"That cache was impossible to find."
"Yeah, did you see those geotrails?"
