Benchmark atlases or ???? Hiking trails on something else?

What sort of hiking trails are you looking for?

Benchmarks do mark some of the larger trails, however there is insufficient detail on the map at scale of 1:200,000 to actually use them to hike.

National Geographic Trails illustrated maps are a better resource for hiking. They are also available through the GaiaGPS app, which is probably the best digital resource for backcountry travel.
