Plan around the marina season

Fees, hours, and seasonal access

Prepare for a river outing

A protected marina inlet does not establish safe conditions on the Niagara River. Review weather, your boat's equipment and the return plan before departure. Ask the operator about launch access and current conditions before committing to a river trip.

Share the docks and respect posted limits

Keep loading areas clear while preparing your boat. In permitted day-use areas, the state allows up to two supervised pets, crated or on a leash no longer than 6 feet. Posted restrictions can exclude pets. Building and other designated-area restrictions also apply; service animals are excepted.

Arrange a slip before arrival

Transient slips require advance reservation and payment through Montana International's Big Six Marina page. For seasonal dockage, use the operator's waiting-list form and ask about a space that fits your vessel. Confirm the applicable season's total price before making a commitment.

Grand Island access and marina orientation

The marina is at 3219 Whitehaven Road, Grand Island, NY 14072. The state marina map shows Whitehaven Road, West River Road, docks, the launch and the marina office. It also marks nearby private land. Use it for orientation rather than as confirmation that every mapped service is open.

Nearby parks on Grand Island

Beaver Island State Park is a separate road stop on Grand Island, with several recreation options. Buckhorn Island State Park offers nature trails through Niagara River wetlands. Use each park's designated entrance for a road visit; their facilities are separate from Big Six.

Choose a launch visit or dockage

Use Big Six as a departure point when its launch is operating, or arrange a transient slip for a planned stop. The four transient spaces make an advance arrangement more useful than assuming a berth will be free when you arrive.

Seasonal marina services

The operator lists ethanol-free fuel, a pump-out service and The Chandler store, which sells groceries, ice and boating supplies. Bring essential equipment before arrival rather than relying on the store for an item you must have. Ask the operator about dock access if you need assistance boarding.
