Kayak or Canoe on Mississippi's only real white water rapids for a half-day, full-day, or overnight trip. The conditions are generally safe for even the most novice boater but ask the operators if concerned. Primitive camping along the river is also available. Canoe $40, single kayak $30, double kayak $50 - all prices per day with pickup and dropoff. Significant group discounts start with 6 boats or more. Drinking on the river is prohibited along most stretches, so ask around before putting in.
