The locals really go to town on horse racing. Races are at Sha Tin or Happy Valley, the tourist board runs a night trip to the latter if you don't fancy heading off alone. The staff are happy to show you how to place a bet (the tickets are pretty complex) and take you ringside to get close to the action. Great fun.
