The district of Sirmaur in the southeast corner of the State is divided by river Giri into two parts, the cis-Giri and the trans Giri. Cis - Giri in which falls, Nahan, the Headquarters of Sirmaur District shows slightly higher development indicators than the other area. The tourists, however, would find places of pilgrimage and interesting legends associated with these in both sides of the river. The princely state of Sirmaur had its capital in Sirmauri Tal, not far from Paonta Sahib. When it was destroyed in a flood, the Capital was shifted to Rajvan and then to Kalsi and during the rule of Raja Karm Prakash (1615-1630), Nahan was spotted as the place fit to be the capital.
At 932m, Nahan is a pleasant looking town on a ridge of the Shivalik Hills. Its climate is salubrious and the town is dotted with gardens, temples and three popular walking circuits, commonly known as the Villa the Military and the Hospital Rounds. The 'Chaugan', a green open space, in the midst of the town is the centre for many cultural events and sports activities.
Himachal Pradesh is not only the land of snow and high mountains but also has lower hills known as Shivalik, where too the tourists can spend their vacations, see the wonders of nature like the big lakes, wild life parks or sanctuaries and the fossil parks etc. One such area is district Sirmaur, where a triangle of 3 important tourist places namely Nahan, Renuka and Paonta Sahib, have attracted many tourists all round the year. There are many attractions available in this triangle. The district headquarter of Sirmour is Nahan. There is no town existing by the name of Sirmour. One can visit these places either in the order we have explained or first visit Renuka then Nahan and lastly Paonta Sahib from Shimla side or the vice versa. Nahan (The District Headquarter of Sirmaur) has a pleasant climate throughout the year.
