Kanyakumari sits about 240 km south of Madurai, roughly a 5 hour drive — popular for the Vivekananda Rock Memorial, Thiruvalluvar Statue and the sunset/sunrise point where three seas meet. A Madurai to Kanyakumari Cab booking is usually done as an overnight or two-day trip rather than a same-day return, given the distance.
Many travellers combine Rameswaram and Kanyakumari into one multi-day trip since both are on a similar southern route — ask us about a combined itinerary.
An Innova or Innova Crysta is popular for this route for extra comfort over the longer drive; a sedan works fine for smaller groups on a budget.
