Adventure Carolina offers a variety of guided kayaking and canoeing trips on Columbia's rivers. The popular "After Work" trip on the Congaree lasts about 3 hours and is ideal for first-timers and families (Tuesdays, Thursdays and Fridays during the summer). Weekend trips range from shorter jaunts to full-day excursions. If floating is more your speed, schedule a tubing trip, which is great for families and friends just looking for a fun, relaxing day in the sun.
