With so many spectacular beaches in the area, a day trip to the county park might seem an unlikely addition to a family vacation itinerary. But Sun-N-Fun Lagoon, an aquatic adventure zone within North Collier Regional Park in Naples, is a world above your average neighborhood playground. Kids can splash and swim in a variety of pools, ride the curves of five water slides or float long a 1,200-foot lazy river. For smaller children, there’s a dedicated “Tadpole” wading pool, with swings and a mini marine-themed water slide. Children under three are free. Kids must be 48 inches tall to ride the full-size water slides.
