Although the interiors of some temples, monasteries and Dzongs [fortress] are forbidden to foreign travelers at present, the tourists can still get a good insight into the unique cultural heritage of the Kingdom. The closure of religious institutions is to ensure that monastic life can continue unhindered.

Paro Valley
One of the best agricultural regions of the country, Paro is also one of the most affluent. Fields cover most of the valley floor, while hamlets and isolated farms dot the countryside. The houses of Paro valley are considered to be among the most beautiful in the country. Paro is also the site of one of Bhutan's most impressive buildings – Paro Dzong. The famous monastery of Traktang and the ruins of Drukyul Dzong are nearby.

Thimphu
Thimphu lies in a wooded valley, sprawling up a hillside on the West Bank of the Thimphu Chhu [Chhu means River]. Thimphu is unlike any other world capital. Small and secluded the city is quiet and there are never the traffic jams familiar in other Asian Capitals. It is often said that Thimphu is the only world capital without traffic lights. Thimphu's main shopping street is a delight not so much for what you can buy there, but for the picturesqueness of the architecture and national costume. Beautiful weaves in wool, silk and cotton, basketwork, silver jewellery, thangkas and other traditional crafts of the Kingdom are available in various Handicraft Emporiums.

Punakha
Punakha plays a primordial role in the history of Bhutan; it was the country's winter capital for 300 years. Punakha Dzong, or Punthang Dechen Phodrang, was built in 1637. The Dzong resembles a gigantic ship exactly covering a split of land at the confluence of two rivers. The history of Punakha Dzong dates back to the year 1328 when a saint named Ngagi Rinchen built a temple there which can still be seen today opposite to the great Dzong. Shabdrung Nawang Namgyel a key figure in the history of Bhutan built Punakha Dzong and his body is preserved in one of the Dzongs temples, Machen Lhakhang. The Dzong was damaged six times by fire, once by floods and once by earthquake. The coronation of Ugyen Wangchuk, the first king of Bhutan, took place at Punakha Dzong on 17th December 1907.

Wangdue Phodrang
Wangdue Phodrang, means ‘the palace where the four directions are gathered under the power of the Shabdrung'. However the popular story has it that the Shabdrung arrived at the river and happened to see a boy building a sand castle. He asked for the boy's name, which was Wangdue, and thereupon decided to name the Dzong Wangdue Phodrang or 'Wangdue's Palace.' Wangdue Phodrang Dzong is perched on a spur at the confluence of two rivers. Its position is remarkable as it completely covers the spur and commands an impressive view over both the north-south and east-west roads. The main road climbs the length of the spur and on the left, across the river, comes the first glimpse of the picturesque village of Rinchengang whose inhabitants are celebrated stonemasons.

Phuentsholing
This small modern town in the south is the gateway of Bhutan for overland travellers. Like all other border towns, it is also a prelude. Phuntsholing is also a fascinating mixture of Bhutanese and Indian, a lively center for the mingling people, languages, customs and goods. On top of a low hill at nearby Kharbandi, a small Gompa situated in a garden of tropical plants and flowers overlooks the town and surrounding plains.
The Amo Chu, commonly known as the Torsa river flows alongside this town and it is favorite spot for fisherman and the picnickers. From Phuntsholing, the road winds north over the southern foothills, through lush forested valleys and around the rugged north-south ridges of the inner Himalayas to the central valleys of Thimphu and Paro. It is a scenic journey; forests festooned with orchids cover the mountains on the other side and exciting hairpin curves greet travellers with colourful sculptures of Tashi Tagye (the eight auspicious signs of Buddhism).

Trongsa
Trongsa means 'the new village' and the founding of Trongsa first dates from the 16th century, which is indeed relatively recent for Bhutan. It was the Drukpa lama, Ngagi Wangchuk (1517-54), the great grandfather of Shabdrung Nawang Namgyel, who founded the first temple at Trongsa in 1543. The landscape around Trongsa is spectacular, and for miles on the end the Dzong seems to tease you so that you wonder if you will ever arrive. The view extends for many kilometers and in the former times, nothing could escape the vigilance of its watchmen.

Bumthang
The Bumthang region encompasses four major valleys: Choskhor, Tang, Ura and Chhume. The Dzongs and the most important temples are in the large Choskhor valley, commonly referred to as Bumthang valley. There are two versions of the origin of the name Bumthang. The valley is supposed to be shaped like a Bumpa, a vessel that contains holy water, and Thang meaning flat place. The religious connotation of the name aptly applies to the sacred character of the region. It would be difficult to find so many important temples and monasteries in such a small area anywhere else in Bhutan.

Mongar
The Mongar district is the northern portion of the ancient region of Kheng. Hardly more than a stopping place surrounded by fields of maize, it was also the first town built on a mountain side instead of in a valley, a characteristic of eastern Bhutan where the valleys are usually little more than riverbeds and mountain slopes which rise abruptly from the rivers, flatten out as they approach their summits. Shongar Dzong, Mongar's original Dzong, is in ruins and the new dzong in Mongar town is not as architecturally spectacular as others in the region. Dramtse Goemba, in the eastern part of the district, is an important Nyingmapa Monastery.

Lhuentse
Lhuentse is an isolated district although there are many sizeable villages in the hills throughout the region. It is very rural and there are fewer than five vehicles, including an ambulance, and not a single petrol station, in the whole district.
Formerly known as Kurtoe, the region is the ancestral home of Bhutan's Royal Family. Though geographically in the east, it was culturally identified with central Bhutan, and the route over the Rodung-la was a major trade route until the road to Mongar was completed. To see and appreciate Lhuentse properly, with its many small villages and ancient temples, you should really explore on foot.

Trashigang
Trashigang is one of the most densely populated districts in Bhutan. After Thimphu, Trashigang is the biggest urban center in mountainous Bhutan. It is the heart of eastern Bhutan and was once the center of important trade with Tibet. There are several goembas and villages that make a visit worthwhile, but it is a remote region and requires a lot of driving to reach.
