Joia Beach sits on Watson Island behind a foliage-lined path that most Miami visitors drive straight past on the MacArthur Causeway. That’s exactly how the regulars like it. Opened in 2020, this upscale beach club occupies a private stretch of Biscayne Bay with Biscayne Bay on one side and the Miami skyline on the other — the kind of golden-hour backdrop that goes full cinematic right on schedule. European-inspired small plates and craft cocktails fuel the afternoon, resident DJs take over as the sun drops, and the vibe slides from barefoot beach lunch to buzzing nightspot without anyone needing to change. Condé Nast called it one of the best beaches in Miami, which is saying something in a city that takes its beaches seriously.
