Grand Cayman is the largest of the three Cayman Islands measuring roughly 196 km2 and is to home of the capital of the Cayman Islands, George Town. The towns on the island are referred to as "districts."
The island is a high-lying reef of "ironshore" (limestone fringes with numerous marine fossils), with a highest elevation of roughly 79 feet (24 meters) above sea level. There is no natural fresh water found on the island, so any fresh water needs must be met by catchments or desalination of seawater. The lack of rivers, however, does account and contribute to the exceptional clarity of the sea.
The eastern side of the island is more undeveloped than the rest of the island, while the western side, which holds George Town and the airport is more developed and a popular tourist destination. Restaurants of all types, night clubs, and resorts can be found on the western side of the island while the eastern district restaurants specialize in a more native Caymanian cuisine.
The district of West Bay features a turtle farm. The majority of Green Sea Turtles are raised for their meat, the theory being that this eliminates consumption of wild animals. Some of the farmed turtles are released, and have good survival rates in the wild. The turtle farm also has several rare Blue iguanas and a caiman on display.
West Bay district is also home to a formation of limestone known as Hell. This is a popular tourist destination for tourists and cruise-ship passengers, and is mostly known for its merchandise of postcards, t-shirts, and souvenirs commemorating a visit there.
Stingray City, which is located a short boat ride from the northern end of Grand Cayman, is a series of shallow sand bars where sting rays are found in abundance and visitors can feed, pet, and interact with the animals. The area is home to southern stingrays can grow with a wingspan up to 3 feet (100 cm), and have become quite accustomed to being handled and fed.
In the southern district of Bodden Town, is the historic house of Pedro St. James, considered the birthplace of democracy in the Cayman Islands. It is also the oldest known existing stone structure on Grand Cayman and was also the first Capital of the Cayman Islands.
The Eastern districts refers to Bodden Town, East End and North Side. In the center of the Island (the North Side district) is the Mastic Trail, a hiking trail through old growth dry forests that used to cover the entire island.
