The largest of the beach communities and the commercial hub is Jacksonville Beach, blending residential, commercial, retail, and industrial sectors.  Many businesses are located along the Third Street corridor, offering a kaleidoscope of shopping, dining, and entertainment options.  This active area offers frequent festivals and celebrations as well as competitive sports events and recreational activities that include golfing, sport fishing, whale watching, nature study, cycling, surfing, wind surfing, and beach combing.  South Jacksonville Beach provides a calmer residential environment and more limited beach access.  The city's location on a barrier island between the Atlantic Ocean and the Intracoastal Waterway creates pristine beaches that remain relative uncrowded.  The Sea Walk Pavilion showcases concerts and festivals nearly every weekend from April through October, while waterfront dining features mouth-watering seafood.
