Head 1/2 mile south of Beach Houses in Paradise on MacArthur Blvd to Bathtub Beach in Stuart, which the locals call "Toddler Beach"...waters so calm and shallow, it's like a bathtub. (There's a large reef offshore that blunts the waves). And there's a lifeguard (it's the most uneventful lifeguard station in the county, because the waters are never rough). The reef also makes for fantastic snorkeling, scuba diving, and windsurfing. A perfect day at the beach for the entire family.
