We went on a weekday night and it was not too crowded. I could find a roadside parking space opposite the botanical garden. You would be fascinated by the variety of flowers displayed here. You could easily spend2-3 hours here. They have a nice cafeteria serving drinks, coffee and sandwiches. The staff is very helpful and will guide you when needed. You won’t realise this is one of the oldest botanical gardens and it’s brand new from the inside.
