What Is Grand Cayman? The Largest Cayman Island Explained
How the island fits together, from George Town and Seven Mile Beach to the North Sound and the quieter east.
In this guide
Grand Cayman is the largest of the three Cayman Islands, a British Overseas Territory in the western Caribbean. It is about 35 kilometres long and home to the vast majority of the territory’s people. So what is Grand Cayman like as a destination? This guide explains how the island fits together before you choose where to stay.
What is Grand Cayman? The short answer
Grand Cayman is a flat, English-speaking island known for Seven Mile Beach, clear water, diving and snorkelling, and a large financial services industry based in the capital, George Town. It is easy to reach from the United States, and it has a wide range of hotels, condominiums and private villas. Its smaller sister islands, Cayman Brac and Little Cayman, are reached by short domestic flights.
The districts
- George Town: the capital, with the airport, the cruise port, banks, shops and restaurants.
- Seven Mile Beach and West Bay: the island’s best-known beach, lined with resorts and condominiums, and the quieter West Bay district to its north.
- South Sound and Bodden Town: residential south-coast areas close to town, with waterfront homes; Bodden Town was the island’s original capital.
- North Side: Rum Point, Cayman Kai and Starfish Point, facing the calm, shallow North Sound.
- East End: the least developed district, known for its rugged coast, dive sites and blowholes.
The island by the numbers
Government figures put Grand Cayman at about 76 square miles, roughly 22 miles long by four miles wide, with its highest point about 60 feet above sea level. The North Sound is a shallow, reef-protected lagoon of about 35 square miles, and most of the coast is sheltered by offshore reefs. With no hills, drive times rather than terrain decide how far apart places feel.
Grand Cayman has five districts. The 2021 census counted George Town at 34,921 residents, West Bay at 15,335, Bodden Town at 14,845, North Side at 1,902 and East End at 1,846; the government’s 2024 estimate for the whole territory is 88,833. The west of the island, from George Town through Seven Mile Beach to West Bay, therefore holds most of the people, restaurants and traffic, while North Side and East End are thinly settled.

The North Sound
The North Sound is a large, shallow lagoon enclosed by a barrier reef. It is where you will find Stingray City and the Sandbar, and its shores at Rum Point and Cayman Kai are some of the calmest on the island. Read our guide to Stingray City for how to visit. The tourism department puts the Sandbar about 25 minutes by boat from Seven Mile Beach; see Stingray City for the rules and how to choose a trip.
Practical basics
- Currency: the Cayman Islands dollar, fixed at CI$1 = US$1.20 since 1974. US dollars are widely accepted.
- Driving: on the left.
- Time zone: Eastern Standard Time all year, with no daylight saving.
- Language: English.
Money, driving and getting around
The Cayman Islands dollar is fixed at CI$1.00 = US$1.227 according to the Cayman Islands Monetary Authority, and the tourism department says US currency is used interchangeably. Ask the provider for an itemized total and confirm what the quote includes. Refer questions about applicable taxes to a local professional.
Traffic drives on the left. The tourism department calls a rental car the most flexible option and says visitors aged 21 and over can obtain a temporary driving permit at rental counters; licence fees were revised from 1 September 2026, so confirm the cost. Public buses run from around 6 am with fares from CI$2.50, carry blue number plates and can be flagged down; the depot is on Edward Street in George Town. Taxis use a fixed fare table rather than meters, for example US$27 from the airport to the Ritz-Carlton for up to four passengers on the Public Transport Unit’s list. Routes, permits and fares are covered in getting to Grand Cayman.
Who Grand Cayman suits
- Families who want calm water, easy flights and a familiar feel.
- Divers and snorkellers.
- Couples looking for a polished beach holiday with good restaurants.
- It suits less well those looking for dramatic mountains or a low-cost trip; the island is flat and prices are high.
