Spanning an area rich with floral diversity in the Eastern Himalayan region, the Sessa Orchid Sanctuary stands as a beacon for nature lovers and botanists. The ideal time to visit this lush sanctuary is during the spring season, which falls between March and April. During this period, visitors have the opportunity to witness a myriad of orchid species in full bloom, their colors and fragrances creating a delightful sensory experience. The climate is also favorable, with moderate temperatures that make trekking and exploration comfortable. Tourists can embark on nature walks and enjoy the vibrant biodiversity without the hindrance of the monsoon rains or the chilly winter frost.
Travelers looking to avoid the peak tourist season, yet still catch a glimpse of the blooming orchids, might consider visiting in the early months of May. The weather remains pleasant before the onset of monsoon showers that start around late May to June, affecting accessibility and making the terrain more challenging. Moreover, since Sessa Orchid Sanctuary is situated at an elevation that provides a cool climate, even the summer months before the monsoon give visitors a chance to enjoy the sanctuary without the extreme temperatures found in other parts of India. However, it's essential to check weather forecasts and consult local advisories beforehand as regional climates can be unpredictable.
