The Blackfoot River in southeastern Idaho is a waterway that offers a range of paddling experiences. Originating near the Caribou-Targhee National Forest in Caribou County, the river flows for approximately 70 miles before joining the Snake River system. The river can be divided into several distinct sections, each offering unique paddling opportunities.

The upper section, from Monsanto Haul Road to the Blackfoot Reservoir, is a calm 22-mile stretch suitable for beginners, though access is limited except during high water months (May-July). Below the reservoir, the 23-mile section from Government Dam to Trail Creek Bridge is popular for its mix of gentle rapids and scenic canyon views, making it ideal for canoes, kayaks, and small rafts. The difficulty ranges from Class I-II in the upper sections to Class IV-VI in the challenging 8-mile Wolverine Canyon section between Trail Creek Bridge and Cedar Creek. This latter stretch is recommended only for expert kayakers, featuring intense rapids and technical whitewater.

The best paddling season is typically May through July when water levels are highest due to snowmelt. However, flows can be affected by irrigation demands, so checking current conditions is essential.

The river corridor supports diverse wildlife and vegetation, with opportunities to spot various bird species and possibly larger mammals like deer or moose. The landscape transitions from rolling hills to dramatic canyon walls, offering stunning vistas throughout the journey.

Key access points include the put-ins at Government Dam, Cutthroat Trout Campground, and Trail Creek Bridge. The nearby town of Blackfoot serves as a good base for river expeditions. The Bureau of Land Management manages five campgrounds along the river, providing options for multi-day trips.

Historically, the Blackfoot River played a crucial role in the region's development, supporting indigenous communities and later influencing settlement patterns. Today, it remains an important resource for recreation and irrigation.

Safety considerations include being prepared for sudden weather changes, understanding the river's variable flow patterns, and respecting private property along the banks. Permits are not required for private trips, but commercial outfitters must obtain proper licensing.

For those seeking a longer adventure, the river offers potential for multi-day trips, particularly in the 23-mile stretch from Government Dam to Trail Creek Bridge, where BLM campgrounds provide convenient overnight stops. The Blackfoot River in Idaho presents a captivating blend of serene floats and thrilling whitewater, set against a backdrop of stunning Idaho wilderness, making it a premier destination for paddlers of various skill levels.
