St. Petersburg, or "St. Pete" as the locals call it, sits between Tampa Bay and the Gulf of Mexico. On the Bay side, downtown St. Pete is laid out on a square grid of numbered streets and avenues, making it easy to find fun things to do both kids and parents will enjoy - The Pier, Great Explorations and more. Long narrow barrier islands create the western border of St. Petersburg, and here's where you'll find white-sand family beaches.
The Dolphin Queen sets off for 90-minute cruises through Tampa Bay every day of the week. They guarantee you will see dolphins, but you may also get a glimpse of sharks, rays, and manatees as they pass by the coast guard station and bird sanctuary.
The Pier Aquarium is the highlight for younger kids. Smaller than other area aquariums, it's entertaining for an hour or so, with eight tanks of sea life including a touch tank.Tropicana Field - The Tampa Bay Rays call this baseball stadium home. You can go to afternoon or evening games during the April-October season, and purchase tickets in advance online. Kids get to run the bases after Sunday games. Check out the Rays Rookies Kids Club page on their web site.
Sunken Gardens - Next door to the museum is a four-acre botanical garden where kids can feed the koi fish or visit the flamingos, parrots, and four-foot-long alligator snapping turtle. (Buy a combination ticket for the museum and gardens.)
Fort De Soto Park Beach - A beautiful clean beach with sand dunes on crystalline blue waters. A sandbar separates the beach from deep water, leaving a shallow pool perfect for toddlers. Amenities include shaded picnic area, snack bar, and restrooms with showers. There's no admission fee, only tolls on access roads. Fort De Soto was originally an outpost during the Spanish-American War, and you can still visit the old fort and see the huge cannons.
Treasure Island - There are actually three beaches on this island: Treasure Island Beach is the wider, more developed middle beach. Sunshine and Sunset beaches are the quieter stretches at either end. You can rent a cabana as a home base and source of shade. There are also covered picnic tables, a sundry shop, and volleyball nets.
Upham Beach - This wide beach is frequented by local parents, a sure sign of kid approval. It's just north of St. Pete Beach, offering a break from the row of hotel towers. There are no lifeguards on duty, but the Gulf of Mexico waters are relatively calm. The Seaside Grille offers quick, casual meals.
St. Pete Beach - Running nearly five miles along sparkling clear water, this soft, white sand beach is great for long walks. It's lined with hotels, most notably the historic pink Don CeSar Resort, where you can enjoy a special lunch even if you're not an overnight guest. You have to find public access points between the buildings to reach the beach. Beach chairs and umbrellas are available for rent, and there are playgrounds on the beach.
Pass-a-Grille Beach - The southernmost beach, just south of St. Pete Beach. It's a quiet, relaxing vibe here and few crowds. Public amenities include bathrooms, outdoor showers and a snack bar serving kid-friendly fare. At the end of the day, the famous Hurricane Seafood Restaurant is a great place to eat grouper sandwiches on the roof and watch the sunset.
