Main Line Canal Greenway Geo Trail: Geocaching

Investigate the foundations of history and discover your own adventure along the Greenway through geocaching- a worldwide hide and seek quest for treasure using GPS!

The Pittsburgh-to-Harrisburg Main Line Canal Greenway™ is a 320-mile corridor that follows the historic path of the Main Line Canal.  It serves as a physical and conceptual connector that improves opportunities for public access, linkage to important destinations, and economic development.  It is not a single, long-distance trail for unimpeded travel.  The Greenway is a signature initiative of Allegheny Ridge Corporation (ARCorp).

As part of the Greenway initiative, ARCorp created the Main Line Canal Greenway GeoTrail – a new and unique way to experience the Greenway.

What is Geocaching?

Geocaching (pronounced geo-cashing) is a growing worldwide game of hiding and seeking treasure. A geocacher can place a geocache in the world, pinpoint its location using Global Positioning Technology (GPS) technology and then share the geocache’s existence and location online. Anyone with a GPS device can then try to locate the geocache. A geocache is any type of container, ranging from a film canister to a metal ammo box, that is hidden anywhere.

A geocaching trail (GeoTrail) is simply a series of geocaches tied together by a common theme. There is not necessarily an itinerary, as we would think of a traditional trail, but rather a series of points of interest in a sort of self-guided goal-oriented plan.
