I am just back from a 7-day holiday in the Darjeeling hills and wanted to report that i couldnt enjoy a single sighting of the Kanchenjunga peaks, due to a permanent cloud/haze which seems to have enveloped the region. I did darjeeling-Gangtok-Kalimpong, but found that thick haze impaired visibility on all days of my trip, and I could only see till the outlines of the adjoining hills with very little detail inside. There was no rain, just a thick haze and overcast skies.
Prior to my trip I had scoured the internet for advice on the best time to visit for clear views of the Kanchenjunga, but only found vague hints that March-May and Sept-Dec are the best times to visit.
So if you are planning a visit there soon and want to view the peak, do check out the local weather conditions ! Also, can someone share whats the best time of the year to get a guaranteed clear view of the Kanchenjunga ?
