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

Built by Henry Flagler in 1896 and rebuilt by his descendants after a 1925 fire, this magnificent Italian Renaissance–style resort helped launch Florida tourism with its Gilded Age opulence, attracting influential wealthy Northerners to the state. The hotel, still owned by Flagler's heirs, is a must-see even if you aren't staying here. Walk through the 200-foot-long lobby, which has soaring arched ceilings painted by 72 Italian artisans and hung with crystal chandeliers. Meet for a drink and a round of eclectic small plates at the HMF, one of the most beautiful bars in the state.

Book a pampering spa treatment or dine at the popular oceanfront Seafood Bar. The $35 parking fee is waived if you spend at least $35 anywhere in the hotel (just have your ticket validated).

The chief landmark along Atlantic Avenue since 1926 is this sunny Mediterranean-revival-style building, which is a member of the National Trust's Historic Hotels of America. Stay a night here or simply walk through the lobby to the parking lot where original garages still stand—relics of the days when hotel guests would arrive via chauffeured cars and stay there the whole season. The bar is a locals' gathering spot.
