Seven Mile Beach is about 6.3 miles long
Two measurements of the beach, from one source
The article that gives the 6.3-mile figure gives a second number in the same breath: about six miles for the uninterrupted sandy beach. Those are not in conflict so much as measuring two different things — the outer bound of what you could call the beach, and the part of it that is continuous sand. Neither of them is seven. Whichever you use, the name overstates the beach by something between two-thirds of a mile and a full mile.
It is a small detail and the first thing many visitors ask about.
It is public, all of it
The beach is public property. You can walk its full length regardless of which hotel, condo or nothing at all you are staying in. There is no gate on this beach and no ticket for it.
Snorkelling is noted near the Marriott, near Government House, and north of the Seven Mile Public Beach area. From the cruise terminals the beach is about ten minutes by vehicle, which is on the tender port page. On the bus it is CI$2, which is US$2.40, and there is no bus on a Sunday or a public holiday — getting around has the hours.
What happened to the sand
Annual erosion has already reduced the beach in places. Then Hurricane Helene, in 2024, left “hardly any sand left in some places”. In August 2025 the Grand Cayman Marriott announced a plan to place 8,000 cubic yards of sand to restore its shoreline.
That plan was announced, and conditions on the day you arrive may differ. What you can take from it is that the width of the beach in front of any given property is not a fixed quantity, and a photograph taken before 2024 is not evidence about this year.
If the width of the sand in front of your hotel matters to you, ask the hotel directly and ask when the photograph on their site was taken. A storm in 2024 and a renourishment plan announced in 2025 are both inside the life of most published images of this beach.
The beach against the boat
Seven Mile Beach costs nothing and it is ten minutes from the terminals, which makes it an easy option for visitors with four hours ashore.
The boats go somewhere else. Not one of the seven listings on this site is sold as a Seven Mile Beach trip — they are Stingray City, reef and Starfish Point trips, working the North Sound on the other side of the island. That is a different day out. How the trips compare is on is it worth it, and what a day with no operator in it looks like is on without an excursion.

Prices per person and per boat are on what an excursion costs. The sandbar those boats are heading for is on the Stingray City page. When to come at all — wet season, dry season, hurricane season — is on the best time to visit.
Frequently asked questions
Is Seven Mile Beach really seven miles long?
No. Wikipedia’s article on the beach puts a generous measurement at just over 6.3 miles (10.1 km), and a realistic length for the uninterrupted sandy beach at about six miles. The name overstates it by roughly two-thirds of a mile at best.
What happened to Seven Mile Beach in Grand Cayman?
Erosion, and one named storm. Annual erosion had already cut the beach back in places, and Hurricane Helene in 2024 left hardly any sand left in some places. In August 2025 the Grand Cayman Marriott announced a plan to place 8,000 cubic yards of sand to restore its shoreline.
Is Seven Mile Beach public?
Yes. It is public property and visitors may walk its full length regardless of where they are staying, so there is no gate and no admission. Snorkelling is noted near the Marriott, near Government House and north of the Seven Mile Public Beach area.
