Relying on your smartphone’s maps can be risky in places where cellular service is patchy. That goes for Gatineau Park, where, despite the fact that its southeast corner is surrounded by the city of Gatineau, Quebec (across the river from Ottawa), staff still recommend people use paper maps, CBC News reports. It’s a big park, after all, and not all of it is in the city. But it’s not just about dead zones and dead batteries: out of date trail information and lack of trail difficulty are also problems. None of these problems, mind you, are unfixable (except, you know, dead batteries).

The paper maps in question include general summer and winter maps, along with trail maps for summer and winter activities (all links to PDF files). They’re not total luddites: here’s an interactive map.
