Cayman Islands

Sparsely populated, mostly flat and partly marshy, Grand Cayman, Cayman Brac and Little Cayman have a corner of the Caribbean all to themselves. The largest, Grand Cayman, is shaped a bit like the Little Dipper and spans about 25 miles (45km) from the lip of the cup on the western end to the tip of the handle on the eastern end.
The Caymans are warm in the summer (May to October), when the average daily high reaches 85ТАF (29ТАC). This is also the rainy season but the showers are brief. Winter (November to April) is drier and cooler, with average daily highs of 75ТАF (24ТАC).
Given that mid-December to mid-April (winter) is the peak tourist season, when rates are substantially higher and beaches and lodgings more crowded, it's best to go in the summer. There is more rain in summer, but it tends to come in downpours that clear as quickly as they arrive.

George Town
George Town's attractions include a modest historical walking tour that takes in the remains of the late-18th-century Fort George and the Cayman Islands National Museum, situated in the town's oldest building. The museum, one of the Caribbean's best, features changing exhibits on the islands' human and natural history. The Cayman Maritime Treasure Museum has dioramas on the islands' seafaring days and a robotic Blackbeard that spins yarns about the Caymans' swashbuckling past.

Pedro Castle
History buffs that promise not to be disappointed by a castle without ramparts, moat or drawbridge might consider dragging their carcass from the beach lounge to Pedro Castle. This imposing Caribbean great house dates from 1780, making it the oldest building in the Caymans, and it's been everything from jail to court house to parliament before recent refurbishments turned it into a museum.

Queen Elizabeth II Botanic Park
If you need any proof that above-ground life is as diverse as the underwater themepark, Grand Cayman's botanic park is hard to beat. A well-marked mile-long trail winds through lush, easy terrain, featuring about 300 native species. The park is home to orchids (in bloom late May through June), iguanas (elusive) as well as parrots and other birds. The nearby Mastic Trail meanders through the old-growth forest that once supplied early settlers with timber.
