Craig McCaw is a reclusive billionaire, but that doesn’t stop him from making billionaire-like purchases, including James Island. The private island, located in British Columbia, has only risen in value, and it’s currently worth $75 million, nearly ten times what McCaw bought it for.

The 780-acre island has a 5,000-square-foot main house, private airstrip, pool house, and a boat harbor for all seasons. The cluster of buildings on the island is Wild, Wild West-themed, and Jack Nicklaus designed James Island’s eighteen-hole golf course. For guests, there are six cottages from which to choose. Famous faces like David Foster, Quincy Jones, and Bill Gates have all vacationed on James Island.
