Children's Discovery Museum Bangkok
You can find the Children’s Discovery Museum Bangkok located in the north of the city near the famous Chatuchak Weekend Market. Just take the BTS Skytrain to Mo Chit or MRT to Kampangphet and then it’s a short walk from there – just make sure you arrive early as the current opening hours are from 10:00-16:00 daily.
