Glen Ellen, California
A shrine for lovers of both open space and literature, Jack London State Historic Park includes 26 miles of hiking trails as well as the cottage where London did much of his writing. There's also a museum devoted to London lore and the haunting ruins of Wolf House, London's dream home, which was gutted by fire before he ever moved in and remained unfinished when he died in 1916.
