Overview

Nixon Sandbar, named after the nearby Nixon estate on Key Biscayne, is one of Miami’s best-known yacht gathering spots. The sandbar emerges across the shallow flats of Biscayne Bay, creating crystal-clear waters just a few feet deep with sweeping views of downtown Miami and the Atlantic horizon.

On weekends and holidays, Nixon fills with yachts, catamarans, and center consoles forming a floating party with music, rafts, and float toys. Weekdays are calmer, making it better suited for families and small groups. Anchoring requires care: depths average 2–5 ft but shift quickly near the deeper channel, and currents can be strong if winds align with the tide.

Local insight: Arrive by mid-morning on a rising tide for the clearest water. Bring fenders and lines if rafting with other boats. Launch and fuel up at nearby Rickenbacker Marina or Crandon Park Marina.

Respect Biscayne Bay: Stay off seagrass, pack out trash, and monitor music volume. FWC officers and Miami-Dade Marine Patrol regularly check the area.
