Right, we haven't got all day you know, so it's back up the raggedy steps, and then there are more steps; the trail's mostly steep from now on.
But very soon, there's an excuse for another rest - the Middle Fall, where the stream drops down a cliff face, to a pool ringed by bouiders, and almost immediately vanishes into the mini gorge. It's real nice here; it's relaxing to watch the fall, listen to the water shooshing down, and look around to see nothing but ravine, trees, and sky.
Enough relaxation already! The Main Fall's ahead; while the Lower and Middle falls are the supporting cast - and among the prime waterfalls in Hong Kong - the Main Fall is the star attraction. The trail is steep, climbing the wooded ravine side, zigzagging upwards.
The path swings round a spur of hillside, and you can look up to see the Main Fall - a ribbon of white amidst the greenery. There are more steep zigzags, a gentler section beside the stream, and - at last - the path arrives at the Main Fall (roughly an hour from Ng Tung Chai village).
The waterfall plummets down the dark cliffs at the rear of a natural amphitheatre; on either side forest clings to the steep slopes (forest that sometimes holds rare birds for Hong Kong); and the amphitheatre opens to the north, facing out towards the hills across the Lam Tsuen Valley.
