Halloween in Bangkok

Bangkok takes Halloween seriously — seriously enough that the party sprawls across two weekends. Khao San Road throws the city's loudest costume street party, a shoulder-to-shoulder parade of zombies, ghosts and improvised brilliance; the club districts answer with themed takeovers, with RCA, Thonglor and Ekkamai booking horror-dressed line-ups and costume-contest prize pots that get bigger every year. Rooftop bars run masquerade nights, hotels stage dress-up dinners, and the malls lean in with haunted houses and family trick-or-treat trails at Siam and EmQuartier. Because October 31 lands on a weekday more often than not, the heaviest inventory falls on the weekend before — so this page tracks the whole late-October window through the night itself, sorted by start time. Costumes are near-mandatory at the club events (door discounts usually reward effort), face paint beats masks in the heat, and the best parties publish tickets two or three weeks out.
