Besides the popular Grand Palace, Bangkok has also Dusit Palace, which is also worth visiting.
Dusit Palace is a complex with 13 royal residences, one of which is the primary residence of the king. Tourists are allowed to walk in some areas in this palace, but inappropriate clothes are forbidden.
Sleeved shirts (even short sleeves) are ok. Trousers or pants for men are ok, but not for women.
Women should have long skirts or dresses. I had pants that day, but a solution to the problem was a purchase of rainbow-colored (alternatively floral) sarong.
There was a store selling sarong near the entry. No cameras and phones were allowed, so we left them in lockers.
In this palace compound, my purpose was to see the 72-room Vimanmek Palace, built in 1900 and entirely of teak, oh beautiful teak (these trees are now endangered in the Philippines and Burma.)
Thanks to Queen Sirikit, this palace is now a museum since 1982. It is is the world’s largest golden teakwood mansion.
Ananta Samakhom Throne Hall is within the compound. It is a former reception hall, which is now a museum. Unfortunately, my companions were too tired and exhausted by the heat so we all decided to walk back to the hotel. I was pretty tired myself. It was so hot I had to cover my skin with the sarong.
