Guides
Plain-language guides built from measured trail data. Every list says how it was made, and unknown stays unknown.
Easy-effort trails around Boulder
Trails our model puts in the lowest effort band: about an hour or less one way with little climbing.
Dog-friendly trails
Trails tagged in OpenStreetMap as allowing dogs.
Trails that pass a viewpoint
Trails that pass a mapped viewpoint.
Trail running starting points
Unpaved trails of a mile or more: a computed place to start, not an endorsement.
Trails that pass a waterfall
Trails that pass a mapped waterfall.
Long trails (8 miles or more)
Trails of eight miles or more, longest first.
Wheelchair-friendly trails
Trails tagged as wheelchair accessible or limited access.
Short walks (under 2 miles)
Trails between a quarter mile and two miles.
