Sikkim does not have any international standard deluxe hotels, however, in the last 3-5 years many tourist class hotels & resorts have sprung up in the main cities & towns, such as Gangtok, Lachung, Lachen, Pelling, Yuksom, Rabongla, Darjeeling, Kalimpong, etc., that offer quality accommodations.

In the smaller towns, accommodation facilities are still quite basic. And during the peak holiday seasons in July & August there is often difficulty in getting rooms. We categorize our tours into 2 types — deluxe & standard based
on the available hotels or resorts.
We have special offers on most hotels in the areas of our operations; for more information on the hotels we use or prices, please click on the link provided here; Our Hotels

Climate
Cold Winters in the month of November to February with minimum temperatures dipping to 4 centigrade during January - February. It is between the month of March and early May when sunshine is quite abundant. Though summer is officially from May to October, Sikkim is almost always wet due to the heavy monsoons, with rains at times continuing for days on ends. Longest recorded nonstop rain is 11 days. September to October is Autumn.

A peculiar feature of Sikkim weather is that though there is a classification of sorts of the various seasons, actually experiences a cold winter from end of November to February and monsoons throughout the year with a little respite during May - June and October - November. Even the winter months can be irritatingly wet and damp with the unpredictable showers.
