The BMA says the Children's Discovery Museums in Chatuchak and Thung Khru will close from 1 October 2026 because the contract to run them has lapsed and a new operator is still being procured. City Hall promises a quick reopening once a winning bidder is picked, but gives no date. For Bangkok businesses that rely on family visitors, such as nearby cafés, shops or tour operators, expect weaker footfall during the October school break until the museums reopen.
