A GPS (Global Positioning System) unit can help you find your way around the city, but they can be useful when camping as well.

A GPS can easily point you in the right direction of the nearest gas station, super market, or even hospital in the event of an emergency. Depending upon what part of the country you will be camping, fire and access roads are often on GPS maps, so they can be a great resource and tool for your trip.

At a minimum, a map of the area should be purchased or acquired from the local ranger’s office or visitor’s center. GPS units are great but rely on batteries or a power connection, and if those aren’t available a backup plan is needed. A map won’t lose a satellite connection or run out of power; it will only fail if you lose it.
