We are planning for a Gangtok trip by the mid of July. But then one of my friends advised me not to plan the trip before September. According to him, monsoon in Sikkim peaks in July and there might be landslides and blocked roads. Is that a factor to be concerned about? If we decide to postpone this trip, then what would be the ideal time to plan our tour again? Is autumn the right season or we should ideally wait till winter sets in? I would like to go for the trip when the weather is at its best. Any idea what could be the best season to visit Gangtok?
