Ideally located minutes from beaches, fine dining, shopping, parks, galleries, Downtown Miami, and MIA.
Nautilus, located between Alton Road and Biscayne Bay, is a residential and waterfront Miami Beach neighborhood with mid-century streetscapes and leafy park blocks. The neighborhood’s character concentrates around the 41st Street corridor near Mount Sinai Medical Center, where cafés, small markets, and everyday services keep the sidewalks active. Architectural cues lean toward low-slung ranch homes, updated mid-century builds, and newer infill tucked behind mature trees. Nautilus Park anchors the area with courts, open lawn, and a steady rhythm of local activity. The Bass and Miami City Ballet add a cultural throughline just south of the neighborhood edge. Sunset Harbour’s marina-front dining scene sits nearby, tying the inland blocks to the water.
