If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.
