Aniirajak has published a map of suggested trails around Iqaluit.
In reality, you can ski and hike pretty much anywhere on the toundra, but the map gives indications of nice route, beautiful lookouts, useful information and safety tips. The map is available for free at the Unikkaarvik Visitor Centre.

The map can also be downloaded onto a smartphone, using a free app that supports PDF maps. Once the map is downloaded, you can track your location on the map using the GPS in the phone, which does not require cell service.
