The correct answer is Palchuram.
Palchuram Pass is a mountain pass in the Western Ghats of India. It connects the towns of Munnar in Kerala and Udumalpettai in Tamil Nadu. The pass is located at an elevation of 2,000 meters (6,600 feet) above sea level. It is a popular tourist destination, offering stunning views of the surrounding mountains and valleys.
The pass is also a major transportation route between Kerala and Tamil Nadu. The road through the pass is well-maintained and is open all year round. However, it is advisable to check the weather conditions before traveling through the pass, as it can be closed due to heavy snowfall or landslides.
