When an engine blew on a flight over the Andes, Teresa Rodriguez Williamson vowed to empower other women to travel--if she survived. Three years later, she's written a book, Fly Solo: The 50 Best Places on Earth for a Girl to Travel Alone, and launched a website where you can find travel companions and dish about your trips (tangodiva.com, $15 annually). For more inspiration, pick up Beth Whitman's new Wanderlust and Lipstick: The Essential Guide for Women Traveling Solo, which combines practical info with anecdotes and interviews.
At Hermail.net, you can get insider advice from over 10,000 volunteers around the world, who have also been known to show visiting women around for the day. Sister site journeywoman.com has more than 100 articles on travel health, solo travel, spa destinations, and more.
