Pirate's Lair on Tom Sawyer Island

Pirate's Lair on Tom Sawyer Island is an artificial island attraction surrounded by the Rivers of America at Disneyland in California, Magic Kingdom in Florida (under the name of Tom Sawyer's Island) and at Tokyo Disneyland in Japan (under the name of Tom Sawyer Island Rafts). It contains caves with references to Disney's Pirates of the Caribbean film trilogy, Mark Twain characters from the 1876 novel The Adventures of Tom Sawyer, and provides interactive, climbing, and scenic opportunities.

History
The area opened in 1956, one year after the opening of Disneyland Park in Anaheim, California.

Prior to the debut of Fantasmic! in 1992, when the south end of the Island was re-built to facilitate the nighttime show, Tom Sawyer Island saw very little change. The Island received major upgrades, new show elements, and a complete re-theming in 2007 when it re-opened as Pirate's Lair on Tom Sawyer Island. The re-theming eradicated much of the previous Tom Sawyer theme in favor of characters and elements from and inspired by the Pirates of the Caribbean film series.

Pirate's Lair on Tom Sawyer Island's opening coincided with the theatrical release of Pirates of the Caribbean: At World's End.

Disneyland Park (Paris)
In Disneyland Park (Paris) in France, Big Thunder Mountain occupies the site which is also in Frontierland.

Hong Kong Disneyland
Hong Kong Disneyland does not have Frontierland (although there will be Grizzly Gulch a similar land set to open 2012). So instead, it features Tarzan's Treehouse in Adventureland in a similar location and is also surrounded by the rivers of Jungle River Cruise.
