If you are looking for a long holiday than some places are also there close to Mussoorie that you can see visit. This will give you the same pleasure as that of Mussoorie.
Surkhanda Devi
For the elder people this temple situated on a peak at a height of 10,000 feet is the best place to visit. But you should be careful as there is a steep climb of 2 kilometers. Legend says that head of Lord Shiva’s fell off here while his dance of death was tried to be stopped.
Dhanlauti
This place is for those who like to watch the nature with silence. Sometimes Mussoorie gets filled with tourists and as such it’s the perfect getaway for rejevunation. Located in the midst thick, virgin forests of deodar, rhododendron and oak, Dhanaulti are all about peace and tranquility. It is 35 km from Mussoorie. For those interested, there are enough hotels and resorts here to put you up. Haridwar is a pilgrim center about 90 km from Mussoorie. One of the four pilgrimages in the Uttrakhand region, this is located on the foothills of Shivaliks. It is the place where the Ganga debouches from the hills on to the plains. The Ganga is the main object of worship; people float offerings of auspicious things. A visit to this pilgrim spot is a lesson in spirituality. Another 24kms from Haridwar is Rishikesh, which as the name implies, is the refuge of rishis (saints and ascetics). There are a number of 'ashrams' of various schools of Hinduism, which offer solace to the mind, as well as nourishment for the body. A unique institution is the Kali Kambli Wala foundation, which supplies blankets free of cost to needy pilgrims- they are expected to return them after use, or gift new ones themselves, for use by other pilgrims whose need may be greater than their own. An engineering marvel is the hanging bridge at Lakshman Jhula across the Ganga, which flows fast, free, and fresh, here. It is also considered to be the access point of three other pilgrim places of Badrinath - Kedarnath, Gangotri and Yamunotri the four great places that combine to make Chardham.
Chamba
Located 31 kilometers from Dhanlauti it is another peace loving tourist destination. Nestled on the bank of the river Ravi, Chamba town complete 1000 years of its existence. The town stands on a plateau on the right bank of the Ravi river valley between Dhauladhar and Zanskar ranges south of the inner Himalayas. This town was founded by Raja Sahil Varman in the beginning of 10th Century. In the genealogical rolls of the Chamba Rajas, a reference occurs of place, which was adorned with highly fragrant Champaka trees and guarded by Goddess Champavati. Chamba valley lies enclosed between two principal spur ranges of the Great Himalaya, the Dhauladhar and the Pangi-Pir Panjal. The sedimentary deposits of the Shivaliks give way to the first granite range in the system, the Dhauladhar. The Pir Panjal runs roughly parallel, to the north but on a converging line, and in between lies the drainage basin of the Ravi, one of the principal rivers of the Punjab. The Ravi arises in two streams, the Kalihain from the glaciers in the Bara-Banghal basin, and the Buddhal from the snowfields of Kugti and Manimahesh. Dividing the two is the outthrust spur of the small Manimahesh range, named after the mountain revered locally as an abode of Lord Shiva. The Buddhal , so named because it resembles an old man's flowing white beard, has after Brahmour, carved out one of the most stupendous gorges anywhere in the Himalaya, which, in it's last portion, degenerates to a fearsome overhang carved out of granite.

Dehradun
