Hills: Mizoram is a land of rolling hills, rivers and lakes. As many as 21 major hills ranges or peaks of different heights run through the length and breadth of the state, leaving of course, some plains scattered occasionally here and there.

The average height of the hill to the west of the state is about 1,000 metres which gently rises to 1,300 metres to the east. Some areas, however, have higher ranges which go up to a height of over 2,000 metres. The Blue Mountain, situated in the south-eastern part of the state is the highest peak in Mizoram.

Rivers: Although many rivers and streamlets drain the hill ranges the most important and useful rivers are the Tlawng (also known as Dhaleswari or Katakhal), Tut (Gutur), Tuirial (Sonai) and Tuivawl which flow through the northern territory and eventually join river Barak in Cachar.

The Koldoyne (Chhimtuipui) which originates in Myanmar, is an important river in the south Mizoram. It has four tributaries and the river is in patches. The Western part is drained by Karnaphuli (Khawthlang tuipui) and its tributaries. A number of important towns including Chittagong in Bangladesh is situated at the mouth of the river. Before Independence, access to other parts of the country was possible only through the river routes via Cachar in the north, and via Chittagong in the South. Entry through the later was sealed when the Sub-continents was partitioned and ceded to E.Pakistan (now Bangladesh) in 1947.

Lakes: Lakes are scattered all over the state. But the most important of them are Palak, Tamdil, Rungdil; and Rengdil. The Palak lake is situated in Chhimtuipui District in southern Mizoram and covers an area of 30 Ha. It is believed the lake was created as a result of an earthquake or a flood. The local people believe a village which was submerged still remains intact deep under the waters.

The Tamdil lake is a natural lake situated 110/85 kms from Aizawl. Legend has it there was once a huge mustard plant in this place. When the plant was cut off, jets of water sprayed from the plant created a pool of water, and thus the name Tamdil which means of 'Lake of Mustard Plant' was born. Today the lake is an important tourist attraction and a holiday resort.
