Certain peaks may reach to 2500 m. Just west of the mountains lie the midland plains, comprising a swathe of land running along central Kerala. Here, rolling hills and shallow valleys fill a gentler landscape than the highlands. In the lowest lands, the midlands region hosts paddy fields; meanwhile, elevated lands slopes play host to groves of rubber and fruit trees in addition to other crops such as black pepper, tapioca, and others.

Finally, Kerala’s coastal belt is relatively flat, teeming with paddy fields, groves of coconut trees, and heavily crisscrossed by a network of interconnected canals and rivers. The Kerala Backwaters region is a particularly well-recognized feature of Kerala; it is an interconnected system of brackish water lakes and river estuaries that lies inland from the coast and runs virtually the length of the state.

These highly facilitate inland travel throughout a region roughly bounded by Thiruvananthapuram in the south and Vadakara (which lies some 450 km to the north). Lake Vembanad - Kerala’s largest body of water - dominates the backwaters; it lies between Alappuzha and Kochi and is over 200 km2 in area. The comparative water-richness of the coastal belt can be partly gauged by the fact that Kuttanad, with its backwaters canals and rivers, itself comprises more than 20% of India’s waterways by length. The most important of Kerala’s forty-four rivers include the Periyar (244 km in length), the Bharathapuzha (209 km), the Pamba (176 km), the Kadalundipuzha (130 km), and the Achancoil (128 km). Most of the remainder are small and entirely fed by the Monsoons.

Districts

Fourteen districts comprise Kerala. The districts are distributed between Kerala’s three traditional regions. Northern Kerala includes (from north to south) Kasargod, Kannur (Cannanore), Wayanad (Wynad), Kozhikode (Calicut), and Malappuram. Central Kerala includes Palakkad (Palghat), Thrissur (Trichur), Ernakulam (Cochin), and Idukki. Lastly, southern Kerala is composed of the five remaining districts: Alappuzha (Alleppey), Kottayam, Pathanamthitta, Kollam (Quilon), and Thiruvananthapuram (Trivandrum).

Mahe, a part of the union territory of Pondicherry, is an enclave within Kerala. Thiruvananthapuram is the state capital. Kochi is the largest city and considered the commercial capital of the state.
