The mountains and valleys of Sikkim never fail to spring surprises on the traveller in search of the picturesque. March to May is the best time to visit Sikkim, tourists prefers to come when the golden paddy fields gently sway under the October-November sun.
Apart from the Dzongri trek in extreme Western Sikkim, trekking inSikkim, particularly to northern frontiers is still in its nascent stage owing to permit formalities or its proximity to the borders. But the hassles are there no more.

The trekking in north Sikkim holds lots of restrictions due to the rich concentration of Herbs and medicinal valued plants. Most of the Northern Sikkim portions  fall under RAP or PAP and National parks. But this particular trek route is one of the most tempting.

This particular trek route is one of the most tempting. The highest point one climb is Lhaba-Pass (4300m) the best part is one can start the trek from either side. It can be start from Tarum Chachu (HOT SPRING) and trek end at Yumthang in Lachung, or Start from Yumthang Lachung and then finish at Tarum chachu in Lachen side.

The trek to Green Lakes, the base camp of Mount Khangchendzonga on the Zemu glacier is one of the most beautiful trekking trails in Sikkim. Green Lakes doesn’t mean there is a lake, but one will see unbelievable stretch of green frozen glacier, which is known by the name Zemu Glacier. The view of Mt. Sinolchu (6887m) there is no other mountain that can equal Sinolchu in beauty and boldness. As mentioned by Doglas Freshfield, who had seen many mountains on earth, Green Lake trek starts from Zeema 6ckm ahead of Lachen. Lachen is a beautiful village itself where we set our base of this trek. Gangtok to Lachen is a day’s journey of 5 - 6 hours by car.

A trek up to Tholung via halts at Tingvoong homestay at Thingvoong is one of the best trekking areas following the northern fringes. The trek demands good fitness and medically sound body so as to meet the challenges like steep trek through thick forest as well as resistance to sleep in makeshift jungle houses, caves, cowsheds etc.
When the night falls, local Lepchas, Bhutias and Nepalese gather at the homestay and entertain the guests with traditional folk songs and dances. Tingvoong is one of the happening villages in Dzongu, the Lepcha reserve.

We can see the intermingling of three communities here – where they live, work and merry make together. All the three enjoy Chang, a local drink made of brewed millet. The fermented millet is put in a slender Bamboo container and the water is taken with the help of bamboo straw. Chang is also a demanding drink among the foreign people.

There are interesting things we get to see as we proceed towards Sakyong Pentok, between Tingvoong and Tholung particularly the swinging cane bridge. A place where accessibility is nil,the Lepchas who are known for their ingenuity in weaving items from canes and bamboos have made bridges out of canes. Log bridges are also made so as to cross smaller rivers.
