Hiking mobile apps for treks in the great outdoors

There's nothing better for clearing your head than taking a hike -- and technology can help lead the way. We've rounded up some apps to take on a trek in the great outdoors.

The app All Trails has a directory of about 50,000 trails with details like distance, time and difficulty of a hike -- as well as activities and highlights of the area.

Once you join the community, you can post photos of your hike and review the trail. The app is free at Apple's App Store and Google Play. But if you want topographical maps and other special features, you'll have to pay $50 a year.

EveryTrail has a ton of guides and maps, and its hiking maps have cool photos that are posted from users right from the trail. The app uses your phone's GPS to follow established paths or you can map your own unique trail. The app is free at Apple's App Store and Google Play. With a $4 upgrade to EveryTrail Pro -- you can download maps to use offline.

What's the outdoors without the threat of poison oak? The U.S. Army has compiled its knowledge of nature in the Wild Plant Survival Guide. The app breaks down plants by what is edible, medicinal and poisonous. There are more than 130 entries with clear photos and descriptions of plants.

If you're an adventure seeker -- try downloading SAS Survival Guide. This is not an app for your average hiker, and it's best to study it before and during your trip.

Based on the 1986 book, the app was designed to bring the text to life. It has illustrated tips for making camp, collecting water and building a fire in different climates. It also features a compass, first aid instructions and a Morse code generator.

Author John Wiseman even stars in videos with great survival tips. The app varies by device at Apple's App Store, Google Play and Windows Phone Marketplace.
