As an avid hiker fortunate to live in the U.S. Pacific Northwest, a location with no shortage of accessible trails, the AllTrails app has long been part of my pre-trek research. It features details on 400,000+ treks with the most crucial information available free of charge.
The size of the AllTrail's database, its complimentary nature and all-around friendly user interface make it an indispensable tool not just for hikers but mountain bikers and trail runners, too, helping it sit neatly alongside the best workout apps.
