Since this beautiful palace is in Alwar, the temperature usually stays high here. And since there is a lake just in front of the Ram Bihari Palace, it would be a good idea to visit when this lake is filled with water and not dried up.
This is why monsoon and winter season is the best time to come here and stay at this palace. The climate is slightly cooler during this period and the lake has more water for you to enjoy.
You will also be able to go for a boating and enjoy being surrounded by the small hills nearby.
How to Get Here
Alwar is a small town in Rajasthan and is well-connected via railway tracks and highways.
