The Lower Taos Box is a great Class IV (tops) run. The run is through a beautiful, tight gorge, with limited access in between the put in and takeout points, so bring any necessary spare paddles or rescue gear should an emergency arise. This run is very popular, especially with commercial rafting trips, so you will not find solitude here. Be sure to check on water flow before you go, as anything below 600 cfs is not recommended. All private boaters are required to register with a ranger or at self-serve stations at each access point - no reservations or fee required.
