Regional Division of the Himalayas
On the regional basis Himalayas are classified according to the location to which they belong. In the previous posts we have discussed the Geographical division of the Himalayas which is based on age of the Formation of the Himalayas in different stages. However, the regional division of Himalayas is not a natural division but a man made. Division of the Himalayas on the regional basis is as follows:-
1. The Punjab Himalayas
2. The Kumaon Himalayas
Between the Satluj and the Kali river is the 320 km long Kumaoan himalaya. Its western part is called Garwhal Himalaya and eastern part is known as kumaon Himalaya. The general elevation is higher as compared to Punjab Himalaya. Nanda devi, Kamet, Trishul Badrinath Kedarnath Gangotri are important peaks. Kumaon himalaya is also the source of sacred rivers like the Ganga and the Yamuna. There are several duns between Middle Himalaya and Shiwalik hills. Nainital and Bhimtal are important lakes
3. The Nepal Himalaya

The Kashmir Himalaya lies almost entirely in the state of Jammu and Kashmir. The average height of this region is nearly 3,000 mt above sea level. This province is marked by number glaciated troughs. The Indus is the most important river which traverse this area diagonally for about 650 km. Northern side o this river lies the imposing Karakoram range. This range has lofty peaks and large number of big glaciers. The second highest peak of the world k2 lies in this range. The Ladakh plateau and the Kashmir valley are two important area of this Himalaya. The chief characteristics of Kashmir Himalaya is high snow covered peaks, deep valleys, interlocked spurs and high mountain passes.
The Himachal Himalaya is mainly confined to Himachal Pradesh. All the three ranges of Himalaya are presented in this section of Himalaya- Zaskar range of the Greater Himalaya, Pir Panjal and Dhauladar ranges of Lesser Himalaya and Shiwalik range of Outer Himalaya. Some peaks of this Himalaya attains the elevation of 6,000 mt. The southern slope of this Himalaya are rugged and forested while the northern slopes are bare. This area has beautiful valleys of Kullu, Kangra, and Lahul-Spiti.
The Kumaon Himalayas lie in Uttaranchal and extend from the sutluj to the Kali River. Its main peaks are Nanda Devi (7,817 mt), Kamet (7,756 mt), Mana (7,273 mt), Trissul (7,140 mt), Badrinath (7,138), Kedarnath (6,968), Jauli or Shivling (6,638 mt) and Gangotri (6,515 mt).

The Central Himalayas
The Central Himalayas extends from Kali river in the west to the Tista river in the east . It stretch for the distance of the about 800 km. All the Three Ranges of the Himalayas are present here. The Great Himalaya range attains maximum height in this portion.
