Animas River Trail
The River Trail is the single greatest thing to do in Durango, in spring, summer, and fall is to walk or bicycle the River Trail. It's seven miles long and goes from 32nd street all the way to WalMart. Jump on at Albertson's grocery or at "Gazebo Park" on 15th street.
Bike rentals are available in town. Bring your kids, bring your camera, bring water and snacks.
