You can find the place easily and they have parking lots for cars/bikes. The entrance costs 15k (local).
This is a nice place for a relaxing stroll. Lots of pretty spots to take pictures. There's a building with hanging photos inside it which will tell you a brief history of this palace.
We came here in the afternoon (around 4pm), the weather is very nice & not too hot.
The place is well maintained & clean. So please don't litter carelessly.
You can take stairs to the gazebo and get a full view of the palace.
