Salmon's whitewater park sits right on the Salmon River as it rolls through its namesake Idaho town, a small community feature meant to give locals and passing paddlers a reason to stop. It's genuinely fickle — it only comes together in a narrow flow window, and plenty of visits find it washed out or too flat to surf. When it is working, it's a fun, low-consequence spot for beginners to get a feel for river surfing. Check current flows before detouring off Highway 93, because this one rewards good timing more than a good plan.
