The ideal streamflow range for a safe and enjoyable run is generally between 500-2000 cfs, with the best time to run the river being in late May through June. The river has been rated as a Class II-III, with moderate rapids and obstacles throughout its 153-mile stretch.
One of the most exciting segments of the Big Hole River is the Maiden Rock Canyon, which spans about 4 miles and includes several Class III rapids, including the infamous "Froggie Rapid." Other notable rapids include the "Diversion Dam Rapid" and the "Notch Bottom Rapid."
To ensure safety and preserve the natural beauty of the river, specific regulations have been put in place by the Montana Fish, Wildlife & Parks department. These include restrictions on fishing and boating during certain times of the year to protect spawning fish, and a requirement for all boaters to carry proper safety equipment, including life jackets and a whistle.
Overall, the Big Hole River provides a thrilling and picturesque whitewater experience for kayakers and rafters alike, and is a must-visit destination for anyone looking to explore the beauty of Montana's natural landscapes.
