The optimal time to visit Tarey Bhir in Namchi, Sikkim, is during the spring months from March to May and again during the autumn season from September to November. During these periods, the weather is most favorable with clear skies and comfortable temperatures, ranging from 10°C to 20°C. Spring heralds the blooming of beautiful rhododendrons and various other flowers, turning the landscape into a vibrant palette of colors. The visibility is high, which allows for uninterrupted views of the lush valleys and the majestic peaks of the Himalayas, including the Kanchenjunga – the world's third-highest mountain. The clear weather also ensures that your visit to the vertiginous viewpoint of Tarey Bhir is both thrilling and safe.
In autumn, the post-monsoon freshness brings out the best in the region's natural splendor. The landscape is still lush, but with autumn hues starting to appear. This is considered one of the best times for photography and nature walks as the air is crisp, and the visibility remains superb. Moreover, the Sikkimese festivals like Dasain (Durga Puja) and Tihar (Diwali) typically fall around this time, offering a glimpse into the region's rich culture and traditions. However, it is important to book accommodations in advance since this is a peak travel season for Sikkim and Tarey Bhir can get crowded with tourists.
