The western United States holds many of the most spectacular wilderness float trips in the lower 48.

Some have easy launches followed by miles and miles of wilderness floating, while others require horses and serious packing to reach the put-in. Exploring wilderness via river is a unique approach that involves everything from long, lazy stretches of lounging and swimming to class V rapids and gut-wrenching whitewater. Hike the side canyons, watch wildlife graze on hillsides and enjoy the treasured landscapes that surround these float trips.

Middle Fork of Salmon River, Idaho

Idaho has a treasure trove of wilderness river trips worthy of a separate list. The Middle Fork of the Salmon is such a gem it’s often referred to simply as the Middle Fork. Flowing through the Frank Church Wilderness of No Return, the river is managed for floaters. Commercial outfitters run under strict permits and private floaters must apply through a lottery draw system for prime dates. The river is largely steep canyonlands and rugged terrain. Hot springs offer floaters a nice place to soak along the way.

Smith River, Montana

Much like Idaho’s middle fork, Montana’s Smith is subject to strict floater rules, designated campsites and a lottery draw for dates. The floating season starts early in April but cold weather can freeze the river over rare cases. May, June, and July are peak season with ample flows for the 59-mile float. Agricultural demands draw down flows during mid-summer but they spike in the fall when irrigation shuts down. Plan for at least three nights and four full days on the river.

Owyhee River, Oregon

Running big water in the high desert is a magical experience. The Owyhee river begins in Nevada and cuts canyons through Oregon. The area is extremely remote, scenic and the river offers a mix of moderate and serious whitewater. Only the most experienced paddlers float the upper reaches while most camp floats run from Rome to Birch for around 5 total days of class I to class III water.

Grand Canyon, Colorado River AZ

One of the longest and most famous wilderness floats in the world is the Grand Canyon. The Colorado River and Grand Canyon combine for a month-long trip through a geological wonderland. Big water, big rapids, hot days, cold nights, side canyon hikes and incredible scenery make this a bucket list for any floater. Entire books are written around this one for good reason. Commercial trips are available for the inexperienced while expert paddlers and oarsmen can apply for a lottery date and make the trip on their own if successful in the draw.

Yampa River, Colorado to Green River, Utah

Over 70 miles (roughly 5 days) of alternating between rapids and flat water as you explore the wonders of Dinosaur National Monument. Rapids up to class IV will challenge you and plenty of mild water leaves time to take in the scenery. The first couple of days run through Dinosaur National Monument until you meet the confluence with the Green River for the final leg. The Green has a number of trip options in itself but with this one, you can check two rivers off your list in one shot.
