Mackay Wilderness River Trips offers multi-day whitewater rafting trips. We operate in Idaho's River of No Return Wilderness on the Middle Fork of the Salmon and Main Salmon rivers. Are trips are top-of-the-line with only the best in safety, guides, food and equipment. Our Kid Wranglers (on all family trips) watch over the kids and not only entertain, but educate them on this amazing primitive area. Both these undammed rivers range in intensity as the summer passes. June we have high Class IV thrills and in August the rivers offer low fun splashy water with lots of sunshine and fishing. From the white sand beaches of the Main Salmon to the majestic crags of the Middle Fork's Impassable Canyon, our guests' every expectations are surpassed!
