Poison Creek

While Idaho is known for a lot of things canyoneering is usually not one of them. But the state does hold a few gems with poison creek being arguably the best technical canyon in Idaho. It's definitely worth checking out if you have the time and gear.

Park on Sand Basin Road (43.4953644, -116.9625189) and head southeast across until you reach the main canyon (don't be deceived by little poison creek). Then descend down into the canyon on a faint game trail (43.4893091, -116.9552783), then bushwack downstream until you reach the narrows.

Follow the stream down the narrows until you reach rappel 1 (20ish feet), the continue down until you reach rappel 2 (65ish feet). Swim across the pool at the bottom of rappel 2 then continue down until you reach rappel 3 (35ish feet), then follow the stream until you reach the end of the canyon. Beware this canyon has flowing water and is slippery in spots. There are obvious bouldering for building anchors for each rappel so bring webbing. Cut and take old webbing you find with you.

Once the canyon ends, take a left and follow the obvious 4x4 track back to sand basin road. Then take a left and hike up the road until you reach your car.
