Atlantic Beach, Florida, is a coastal city in Duval County, known for its serene beaches, vibrant community, and rich history as an esteemed vacation destination dating back to the early 1900s [1] [2] [3]. It is the northernmost of Jacksonville's three beach communities, which also include Neptune Beach and Jacksonville Beach [4].

According to www.iAsk.Ai - Ask AI:

Atlantic Beach maintains its own municipal government despite the 1968 consolidation of most Duval County communities with Jacksonville, though its residents participate in Jacksonville's mayoral elections and have representation on the Jacksonville city council [3]. As of the 2020 United States Census, the population of Atlantic Beach was 13,513 [3]. The city spans a total area of 13.0 square miles (33.6 km${}^2$), with 3.5 square miles (9.0 km${}^2$) being land and 9.5 square miles (24.6 km${}^2$) being water [3].

The city's development was significantly influenced by Henry Flagler, who extended the railroad to Mayport in 1900 and built the Continental Hotel, a 250-room summer resort [3] [4]. Although the Atlantic Beach Corporation went bankrupt during World War I and the hotel burned down in 1919, land sales resumed, leading to the town's incorporation in 1926 [3]. Further growth was spurred by the establishment of the Mayport Naval Station and the construction of the Mathews Bridge [3].

Atlantic Beach offers a blend of activities and attractions. The Beaches Town Center, located where Atlantic Beach and Neptune Beach meet, is a pedestrian-friendly hub for dining, shopping, and nightlife [1] [5]. Notable dining establishments include Coop 303, known for its modern Southern menu and rooftop dining; Poe's Tavern, an eclectic pub; and Salumeria 104, an authentic Italian restaurant [1] [5]. For beverages, visitors can explore Grey Matter Distillery, which produces small-batch spirits, or Reve Brewing, a stop on the Jax Ale Trail specializing in craft beers [1] [5].

Outdoor enthusiasts can enjoy Kathryn Abbey Hanna Park, situated between Atlantic Beach and Mayport, offering over 20 miles of hiking and biking trails, a 60-acre freshwater lake for kayaking, and 1.5 miles of beachfront, including "The Poles," a premier surf spot [1] [5]. The park also provides camping and cabin rentals [1]. The Atlantic Beach Farmers Market is held every Sunday at Jack Russell Park, featuring local produce, crafts, and live music [1]. For water-based adventures, Adventure Kayak offers guided kayak and paddleboard tours of Northeast Florida's waterways [1].

Accommodations range from the upscale One Ocean Resort & Spa, the city's only high-rise on the beach, to more affordable options like the Seahorse Oceanfront Inn in nearby Neptune Beach [4] [6]. The area is also recognized for its natural beauty, including majestic ocean dunes and a wilder, less manicured coastline compared to other parts of Florida, providing a habitat for threatened animals like gopher tortoises and indigo snakes [7].
