Arriving at Tai O (大澳), the village on the west coast of Lantau that has been fancifully dubbed the "Venice of Hong Kong", we're expecting to just stroll along through the housing clustered by creeks, then by the mangroves just to the south.
But at the bus stop, there's a lady standing by a map board showing the route of motor boar rides, encouraging us to go for a trip. It costs just HK$20 for a 25-minute ride, which includes a spot of dolphin watching as well as cruising along creeks past stilt houses.
Well, that sounds like fun - so I hand over the money, we clamber into the boat, by fishing boats with Little Egret watching for small fish, the boat soon fills up, and we're off, speeding out into the mouth of the Pearl River.
