The best months for trekking and touring in
Sikkim are Oct-Nov-Dec
and Jan/March-April-May and part of June. However, Sikkim
is for all seasons and all reasons. The Rhododendron flowers
are at the best from May to June end. In Dec and Jan there
are liable to be heavy snowfalls at the heights. The forests
of Sikkim are still intact. Trekking in Sikkim is very different
from Nepal, as trekkers are not allowed to roam unaccompanied
through the hills as that of Nepal. Foreigners must form
a group of at least 2 persons.
