From my own experiences about how complicated dealing with travel operators can be, and how it becomes a source of constant worry if the trip you have been planning for so long shall actually be hassle free and would let you have a great time rather than be a source of constant worry. It can be a pretty intimidating task to find people you can actually plan your holidays through while also being sure it would be executed as you thought. Those experiences from my own travels through the country and beyond and working from my own experiences, what I have sought out to do is to streamline things so that you do not have to face those issues again.
Lachen is a high altitude town in North Sikkim. It is located at an elevation of 9100 ft above MSL. The word Lachen means “big pass”. The town is being promoted as a tourist destination by the Sikkimese government. The town forms the base to The Chopta Valley and Gurudongmar Lake (17,300 ft). An annual Yak race, The Thangu is held here in summer
Lachen is about 129 km from Gangtok and can be reached via a six-hour road journey. A short two-day-long trekking route also connects Yumthang Valley to Lachen. It has a population of around 1000. Lachen has its own system of rules and regulations called Dzumsa. The heads of the Dzumsa are known as Pipon & Gyenbos

Lachung is a small high altitude village in the North district of Sikkim and is near the border with Tibet. Lachung is at an elevation of about 9,600 ft or 3,000 m. The word Lachung means “small pass”. The town is approximately 125 kms from the capital Gangtok
Before the annexation of Tibet in 1950, Lachung was a trading post between Sikkim and Tibet, after which it was closed down. The town’s economy has been boosted by tourism in recent years as the region has been opened up by the Sikkimese government. Tourist come from all over the world to visit the town between October and May, mostly on their way to the Yumthang Valley and the Lachung Monastery.
During winter, the town is usually covered in snow. Lachung is also the base camp for Rhododendron Valley Trek which starts from Yumthang Valley and ends at Lachen Valley. Yumesamdong and Yumthang valley are places to visit from Lachung.
Dzongu is a triangular region in North Sikkim. It is bounded by the Teesta River in the south-east, Tholung Chu River in the north-east and by mighty mountains in the west. It borders the Kanchenjunga Biosphere Reserve.
Dzongu is a village in North Sikkim which is about 70 kms from Gangtok and has been established as an official reserve for the Lepcha people, the aborginal inhabitants of Sikkim. The Lepchas have strong ties with nature and have lived here for centuries. An understanding of their culture, customs and language helps to foster an appreciation of the beautiful mountains, deep forests and the emerald-colored Teesta River.
The region sees little tourist activity and hence seems almost untouched. It is sparsely populated and most of it is covered with dense vegetation. Rice fields and Cardamom plantations can be seen near the villages. Now the Sikkim government has been promoting homestays in this region and a lot of nature lovers visit this place for a relaxing trip.
