The Greater Bragg Creek Trails Association has a map app for both Apple and Android covering the Bragg Creek area trail system. Produced by Trailforks, a trail database website owned by Pinkbike the app includes a map and trail descriptions as well as background information on riding the area. It is primarily aimed at mountain bikers and is positioned by the GBCTA as a fundraiser, with in-app donations and trail volunteer information.
Unfortunately it is, in my opinion, way overpriced at $14.99. This review is somewhat limited because I can’t justify buying the app. I have the excellent paper map for only a buck more, and when I am out in the area I can refer to the extensive signage at every junction. The only reason I can see to purchase the app is to support the GBCTA, or if I were a visitor who wanted to know my current location and it’t GPS coordinates. Here are the links to Apple, and to Google play for the Android version.
