36 Best Sights in Palm Beach and the Treasure Coast, Florida

Housed in the St. Lucie County Aquarium and run by the Smithsonian Institute, whose research facility next door is where scientists study local ecosystems (once-monthly tours are organized), this facility has a 3,000-gallon coral-reef tank, originally located in the National Museum of Natural History in Washington, D.C. The parklike setting, where children love to play, makes it an ideal picnic destination. Admission is free on the first Tuesday of every month.

Despite widespread misconceptions of its members-only exclusivity, this privately endowed institution—founded in 1936 to encourage appreciation of art, music, drama, and literature—is funded for public enjoyment. The Esther B. O'Keeffe gallery building artfully melds an exhibition hall that houses traveling exhibits with a 700-seat theater. A library designed by prominent Mizner-peer Maurice Fatio, a children's library, a botanical garden, and the Philip Hulitar Sculpture Garden round out the facilities and are open daily. 

When the waves robustly roll in, the surfers are rolling in, too. Beginning surfers are especially keen on Stuart Beach because of its ever-vigilant lifeguards, and pros to the sport like the challenges that the choppy waters here bring. But the beach is equally popular with surf fishers. Families enjoy the snack bar known for its chicken fingers, the basketball courts, the large canopy-covered playground, and the three walkways interspersed throughout the area for easy ocean access. Amenities: food and drink; lifeguards; parking (no fee); showers; toilets. Best for: surfing; swimming.

Beautiful sand dunes and verdant grounds await at this quiet turf immediately north of the last swath of development before the drive to the Sebastian Inlet. It's a perfect place to commune with nature, or it's a good spot if you want to feel like you own the beach, as sometimes there's no one except you. Children will delight in the pirate-ship-theme playground on site, and there are plenty of picnic tables (but no grills) plus lots of shade throughout the landscaped section beside the beach. Amenities: parking (no fee); toilets; showers. Best for: solitude; swimming.

A favorite for local surfboarding teens and the families at the nearby Disney's Vero Beach Resort, the park is nestled in a residential area at the end of Wabasso Road, about 8 miles up from the action on Ocean Drive and 8 miles below the Sebastian Inlet. Aside from regular amenities like picnic tables, restrooms, and a dedicated parking lot (which really is the "park" here—there's not much green space—and it's quite small, so arrive early), the Disney crowd walks there for its lifeguards (the strip directly in front of the hotel is unguarded), and the local crowd appreciates its conveniences, like a pizzeria and a store that sells sundries, snacks, and beach supplies. Amenities: food and drink; lifeguards; parking (no fee); showers; toilets. Best for: surfing; swimming.

This 12-acre beach park is popular with local families who enjoy the lovely Brazilian-walnut hardwood boardwalk, plethora of parking spots, and sail-shade canopy-covered walkways and benches. Kids will get a kick out of the playground and adorable large sea turtle sculpture (grown-ups will appreciate that it was made of repossessed metal from an oil rig by a local artist). Free beach wheelchairs are available, as are umbrellas and lounge chair rentals for a small fee, and a concession dishes up sandwiches, salads, and snacks like ice cream. Divers love the four sunken ships off the coast as part of Florida's artificial reefs program. Amenities: lifeguards; food and drink; parking (fee); showers; toilets. Best for: snorkeling; sunrise; sunset; swimming.
