Bangkok. Chulalongkorn University.

When in Bangkok, you must visit Chulalongkorn University, the top university in Thailand. The campus buildings are beautiful and unique, and you can rent a bike to explore the campus. However, make sure to check if it's a holiday. When I visited, it happened to be a Thai holiday, so there were no classes, and the cafeteria and museum were closed. It was a bit disappointing, so I'll make sure to visit again next time I'm in Bangkok. When visiting a university, you must try the cafeteria food, visit the museum and library, and chat with some students to make the experience more interesting!
