Rail journeys in Kerala can be scenic and more comfortable than traveling by car. The KK Express—which travels from Kanya Kumari, at India's southern tip, all the way up to New Delhi—is a good train to take through Kerala, as is the Kerala Express and the Jan Shatabdi. December is a major pilgrimage season, so you'll need to book tickets in advance if you're traveling during this period. Check with KTDC for the latest schedules and fares, or try www.indianrail.gov.in or indiarailinfo.com, and use a travel agent or your hotel's travel desk to make bookings, unless you don't mind standing in a sometimes-unruly line at the train station.
