During this time, the waterfalls are at their full glory, with a high volume of water flowing down the rocks, creating a spectacular sight. However, it's important to note that heavy rainfall can sometimes affect the accessibility and safety of the viewing points, so it's advisable to check the weather conditions and road status before planning your visit.
