Often you can download and print maps from websites, and software companies even provide high-quality topographic maps that you can customize and download to a device or print at home. Outdoor gear shops also provide excellent maps for particular trails, such as the Appalachian Trail. These sometimes include helpful features such as elevation profiles that give you an idea of the type of terrain you’ll encounter along the way. Many maps also have waterproof coatings, which can extend the life of your map in wet weather.
