Kupup Lake, also known as Elephant Lake due to its resemblance to an elephant in shape, is a stunning high-altitude lake situated near Zuluk in the state of Sikkim, India. The best time to visit Kupup Lake is generally between the months of April to June when the weather is relatively serene with a delightful temperature range that allows for clear visibility and comfortable sightseeing. During this season, the flora around the lake is in bloom, adding to the picturesque beauty of the area with vibrant colors and lush green landscapes. The summer months provide a respite from the biting cold and the lake is accessible as the roads are clear from snow.
Alternatively, photographers and adventurers might want to consider the month of September to October, following the monsoon season, when the skies are most likely to be clear and the newly washed landscape sparkles under the autumn sun. This period is also favorable since it avoids the heavy monsoons that Sikkim experiences, which can make travel to the lake difficult due to the possibility of landslides and poor visibility. However, travelers during this time should be prepared for colder temperatures as winter approaches. It’s imperative to check road conditions and weather forecasts before planning your trip as the lake is situated at a high altitude and the weather can be unpredictable. It's also important to note that the region may require special permits for visitors, given its proximity to international borders.
