Discounted iPhone Apps for Stranded Travelers

The recent eruption of Iceland's Eyjafjallajokull volcano disrupted air travel and left many people stranded in unfamiliar cities, so Lonely Planet decided to offer free downloads of 13 of its European iPhone travel guides for a few days. Now, as flights resume, you can download guides to Paris, Rome, Amsterdam, Barcelona, Berlin, London, and more at a discounted price of $4.99 until April 30.

While you're outfitting your iPhone, download apps from Avego or Carticipate to help locate carpool opportunities. The Trails app will help you keep track of hiking routes and VegOut will locate vegetarian restaurants while you're on the go. You can even enter to win a trip to Hawaii with the Sierra Club's Eco Hero app.
