This map shows the Central Loop and the Northwest Loop. The Central Loop traverses the Boston Mountains of the Ozark Plateau, the Buffalo National River corridor, and the Arkansas River Valley. The route passes by the Upper Buffalo Headwaters Trails and the Syllamo Trails.
The Northwest Loop climbs and drops between the Springfield Plateau and the Boston Mountains of the Ozark Plateau. The paved Razorback Regional Greenway makes for easy travel between Fayetteville and Bentonville. The route passes by the Upper Buffalo Headwaters Trails.
I have enjoyed owning several of the maps produced by Adventure Cycling. They are of great quality and with greater detail than you could imagine needing, until you do. I confess that I've never taken one on the road, but I like to consider the recommended routes in areas I'm familiar with. Thus the title "dry lab". You can find more meaningful reviews, but I'm sure there are others who just like good maps.
