Get wet and stay cool during Mississippi’s heat of summer at Geyser Falls, which features a variety of water-themed attractions. From the 1,200-foot lazy river to the backwards waterslide to Mt Everwet’s three six-story speed slides, there is plenty to keep the kids pruning all day. Cabanas can be rented daily and the Beach Club provides a full-service restaurant, tiki bar and live music. Pricing is based on height, with Saturdays being the most expensive days to visit. The park is open daily between Memorial Day and end of July, and weekends in May, August and Labor Day.
