Air
Thiruvananthapuram (Trivandrum) of neighbouring state Kerala, is the nearest international airport, with direct flights from the Middle East, Singapore, Maldives and Sri Lanka. And is served by Air-India, among others. From there it takes about three hours by train or bus or taxi. The taxi charges are pretty cheap, about Rs 9-10 per km, and should be around Rs 1000 (US$22 Approx), for a trip to Kanyakumari from the ThiruvananthapuramInternational Airport.
Alternatively, if you cannot reach Thiruvananthapuram directly from your place, you can reach Chennai (Madras) the state capital and then take either train or bus to reach Kanyakumari. Note that travelling to Kanyakumari is a bit tiresome via road, especially for Westerners, as the travel time is about 14-15 hours and the climate is pretty hot (30-35 degrees during summer and 25-30 degrees during winter) throughout the year. Insist on an II tier air-conditioned coach as this is pretty cheap, about Rs 1200 (US$27). A local flight travel to Thiruvananthapuram is also a viable option, but the ticket prices are slightly higher, ranging from Rs. 1500 and can go up to anywhere around Rs. 5000. In India, the faster you book/plan your travel, the more you save on tickets.
Alternatively reach Kochi, Kozhikode (Calicut), Bangalore, Bombay, New Delhi, Kolkata and then by train.
