Who paints all the trail blazes? Who clears all the blow-downs and debris? Ever seen the occasional ladder and handhold of rebar? Where does that come from? Trail maintenance crews, that’s where.
Behind all that beautiful scenery is the hard, grunt work of men and women who maintain your trail. My hiking buddy in New Jersey is a volunteer trail maintainer for a section of the Appalachian Trail. He scouts his section regularly, clears debris, refreshes blazes with white paint, notes any larger problems, and files a report to his manager.
Some improvements are major and require the paid (minimum wage) services of restoration crews. Check out this article on the remaking of “Tuck’s Trail” in New Hampshire. As you can see, this is a huge job, which also includes the delicate relocation of fragile plants.

Yosemite maintenance on the Pacific Crest Trail
I took the photo above on the Pacific Crest Trail, in Yosemite. The man riding the lead horse was on his way to saw up a large pine that had fallen across the trail .
The worst hiking day I ever had, was thru-hiking during a windy, late-season snowstorm on the Appalachian Trail. Blow-downs covered the trail everywhere, and hikers had to crawl in the snow, under, over, and around busted limbs and branches. Only two days later, while recuperating in town, I met several hikers just coming in. When I asked them about the blow-downs, they said most of them were already cleared; branches and limbs had been cut and pushed to the sides of the trail.
Hats off to all trail maintainers!
