The Rock Garden in Namchi is an exquisite spot surrounded by the rich flora of Sikkim. The most recommended time to visit is between March to May and October to mid-December. During these months, the weather is pleasant with minimal rainfall, allowing visitors to enjoy the picturesque garden and its surroundings comfortably. In spring, from March to May, the temperature ranges from 10°C to 28°C, which is ideal for sightseeing and outdoor activities. The spring season also brings out the vibrant blooms in the region, making the garden a photographic haven with the flowers in full splendor.
Alternatively, autumn, from October to mid-December, is another good season to visit the Rock Garden. The post-monsoon clarity in the air renders crisp views of the Himalayas framing the garden. The temperature during these months tends to vary from around 10°C to 16°C, offering a cool and refreshing climate for visitors to explore the terraced landscapes and cultural exhibits such as replicas of the Char Dham. It's also the prelude to the peak tourist season, so visitors can enjoy the sights without the crowds that come during winter holidays. However, do note that winters can be harsh and cold with temperatures sometimes dipping below freezing, so if you're planning a visit during this time, ensure you are well-prepared with suitable warm clothing.
