Missoula Parks & Recreation
Greenough Park
Greenough Park Trail is a 0.8 mile loop described on TrailLink as “one of urban Missoula’s best”.
“…. Rattlesnake Creek …. courses through the park’s center. Cottonwoods and conifers are thick throughout, as are willows and other woody and herbaceous plants. It’s a great place for bird-watching” “Several dirt paths wind through the trees and along Rattlesnake Creek”
Kim Williams Nature Trail 4.2 miles from TrailLink: the trail “…meanders alongside the Clark Fork River in downtown Missoula. It connects to the Riverfront Trail, giving users an uninterrupted 4 miles of trail from which to enjoy the river or access Missoula’s neighborhoods, commercials areas, parks, and the university.”
Riverfront Trail 3.5 miles “follows an abandoned right-of-way along the old Chicago, Milwaukee, St. Paul and Pacific railroad, commonly known as the Milwaukee Road.”
