Les Bordes, France

This 1,400-acre estate is nestled in the Loire valley south of Paris and is one of the most exclusive and difficult golf courses anywhere in the world. Built by the multi-millionaire owner of the Bic pen and razor company along with a Japanese friend, Les Bordes is located in a stunning setting within the countryside. Future plans are to build a hotel, lodges and a second course. One of the highlights is the beautiful clubhouse with old, oak beams and a rustic vibe along with enormous fireplaces and deep leather chairs. Initiation fees are unknown.
