Robber's Cave, locally known as Gucchu Pani, is one of the most popular tourist destinations in Dehradun, Uttarakhand, India. The ideal time to visit this natural cave is during the summer months from March to June. During this period, the weather is pleasantly warm, and the water levels in the cave are just right for exploring the stream that runs within it. The temperature ranges from 17°C to 35°C, making it perfect for visitors to enjoy the cool waters and the beautiful natural formations without the discomfort of extreme cold or heat. Summer also allows for a great opportunity to witness the unique phenomenon where the stream suddenly disappears into the ground and reappears again after a few meters.
Alternatively, the post-monsoon season, which is from September to October, is another favorable time for a visit. During these months, the verdant surroundings of the cave are at their greenest, having been rejuvenated by the rains. The climate during this time is moderate and inviting, with minimal chances of rainfall disrupting your plans. It's important to avoid the monsoon season, from July to August, when the water level is high, and the currents strong, making it risky and less accessible for tourists. Also, during the winter months from December to February, the cold can be quite biting, making it less ideal for enjoying the water activities in the cave.
