Gaia is one of the more popular apps for maps and navigation, and their website is a filled-out version of that app, offering various resources for hiking, backpacking, off-roading, hunting, mountain biking, backcountry skiing, and fishing. From maps and permitting info to volunteer opportunities and merchandise, Gaia truly is your one-stop outdoorsy info center.
As an app, many folks rely on it as their sole form of navigation.
It’s important to remember that doing so is a bit foolish and somewhat dangerous. If you enter an area without a cell signal, if your battery dies, if your phone malfunctions or gets dropped, and you don’t have a map or guidebook or something else hardcopy, imagine the bewilderment when you can’t access your only navigation tool. I love using it as backup or confirmation, being able to watch myself move as a little arrow on the map on my screen if I have a moment of am-I-going-the-right-way, but I never rely on it as my sole form of navigation.
As an app, its detailed topographical maps are unrivaled. With the push of a button, you can see exactly where you are, often accurate to within ten feet.
