You should have at least 2 to 3 days to explore Kangra and its prominent attractions comfortably. This timeframe allows you to visit key places like the Kangra Fort, Masroor Rock Cut Temple, Baijnath Temple, and explore the natural beauty of places like Palampur and the Kareri Lake. It also gives you enough time to immerse yourself in the local culture, enjoy the serene landscapes, and indulge in some trekking or outdoor activities.
