Miami Beach Marina is a working South Beach marina at 300 Alton Road, near the southern tip of Miami Beach. Its main service is dockage for boaters, not a bundled water-sports park. Suntex, the marina operator, lists 400 slips for vessels up to 250 feet, with monthly, annual and transient stays. The location offers access to Biscayne Bay and the Atlantic without fixed bridges on the approach described by the marina.
Booking a slip
Start with the marina’s official slip and amenities guide. It links to online transient-slip booking and an inquiry form for longer stays or questions about vessel size, shore power and current rates. Do not assume a slip is available just because the marina has capacity on paper; confirm dates, vessel dimensions, draft, power needs and the latest rate before arriving. Boaters can also reach the marina through its official contact page.
Services on site
The operator lists shore-power connections, fresh water, diesel and Rec-90 fuel, pump-out service, dock assistance, security patrols, Wi-Fi, restrooms and laundry, covered parking, a marine store and a deli. Its dock assistants help with arrivals and departures, but service hours vary by day; check the current schedule on the slip page. The marina also lists casual and fine dining on site, which makes it convenient for a meal before or after time on the water.
Visiting without a boat
You can use the marina as a starting point for a South Beach waterfront outing, but the slips and working docks are boating facilities; do not assume unrestricted public access to them. The marina’s official attractions directory lists independent dining and activity operators, including boat tours and other water activities. Book those services with the named operator and verify its departure point. The marina itself does not promise that every activity is available on every day.
For a private cruise rather than dockage, compare our Miami Beach yacht-rental guide and check the actual boarding location before paying. For the marina, the most useful next step is to choose whether you need a slip, a waterside meal or a separately operated tour, then follow the relevant official booking link.
