Montana State Parks ( is partnering with City of Great Falls Park & Recreation to open Cochrane Dam, owned by NorthWestern Energy, for public crossing on Saturday, September 29th from 10am to 3pm in celebration of National Public Lands Day.

This only happens a couple times a year: ride, run, walk across Cochrane Dam!  There are multiple ways to enjoy this event. You can access the dam from the Rainbow Trailhead at the end of Rainbow Dam Rd and take a leisurely 2.5-mile hike or bike ride along the River’s Edge Trail to the dam. Once there, relax on the dam and take in the views If you are a little more adventurous, take the single track from Rainbow Trailhead; medium difficulty and approximately 4 miles.

For a full day adventure, park your vehicle on the South Shore trailhead, Lewis and Clark Overlook and take one of the many trails along the South Shore to Cochrane Dam (3.5 miles), cross it and then head to Rainbow Trailhead on the North Shore. Remember to set up a shuttle.

This event made possible through Montana State Parks, Giant Springs State Park, NorthWestern Energy, River’s Edge Trail Foundation, and City of Great Falls Park & Recreation.
