For a first trip, Kullu has a nice mix of popular spots and hidden gems; must-visit places include Raghunath Temple, Bijli Mahadev Temple (great views after a short trek), and Beas riverside areas, while for less crowded places you can explore Naggar (peaceful with castle views) and Jana village known for natural beauty and waterfalls; for food, try local Himachali dishes like siddu, dham, and trout fish if you’re non-vegetarian, and overall the best experience comes from relaxing by the river, doing short village walks, and exploring local cafés.
