Kovilpatti sits on NH-44, the main north–south highway running from Varanasi to Kanyakumari, giving it decent road connections across southern Tamil Nadu. Frequent buses run from Tirunelveli (55 km) and Thoothukudi (50 km) throughout the day.
The railway station is about 2 km from the town centre, with trains to Chennai, Madurai, and Thiruvananthapuram. The nearest airport is at Madurai, roughly 95 km away.
