Baijnath temple is open 12 Months 365 days. However , my personal experience suggest January – March as the best time to visit the temple. You will surprised to witness the aroma near the temple and I bet only temple where a sweet aroma can be felt. One can understand from where this aroma is coming. Where ever you go divine aroma will follow.
Refer to Baijnath Itinerary on how to plan your trip.
