Tour Fort Sumpter on SpirtitLine Cruise. This year there was a bad thunderstorm and we didn't go. Departures are either from Liberty Square (near the aquarium) or at Patriot's Point. 5 and under are free, kids are $10 and Adults are $17. Patriot's Point home of the USS Yorktown is a separate museum and the prices are within a dollar of the Fort Sumpter tours with an additional $5 per day parking cost. Total for both for our family would be around $180 plus food.
