Po Kwu Wan is a quiet little bay in Sai Kung near the West Dam of Highland Reservoir with a little something extra. A semi-circular concrete bay that was used by the fishermen to farm fishes. Now, it’s abandoned with a great view of the ocean and beautiful blue water and a short hike past the Sheung Yiu Folk Museum.

Getting to the trail start for Po Kwu Wan

The trail start for Po Kwu Wan is the Pak Tam Chung Country Trail, which you can reach by walking from Pak Tam Chung Car Park if you park there.
For the bus, take 94 from Sai Kung and get off at Sheung Yiu Bus stop and cross the road to the trail start that is well marked. You can see the bridge that takes you over the river so it’s hard to miss.
Pak Tam Chung Country Trail/Sheung Yiu Family Walk
The trail is well paved with informative signs scattered along the way. You can see the bend of the river at the beginning but then it’s mostly just vegetation.
The signs give you information on the vegetation and there are some mangroves. After about 15 minutes, you’ll reach the lime kiln that the Hakka villagers used about 100-200 years ago.
Sheung Yiu Folk Museum

A little further on is the Sheung Yiu Folk Museum. It is a refurbished house of the Hakka people that lived here completed with reconstructed rooms. It is free to visit and their opening hours can be found here.

There is also a small pier across from it where the villagers used to get kaito to go to Sai Kung. Next to the pier is a pavilion where you can take a break.
Carry on once you are ready and follow the trail down. Don’t go up to Sheung Yiu Country trail but stay on the flat path. When you reach the junction, go left to Hei Tsz Wan. It’ll take you past some abandoned village houses up a flight of stairs.
Turn left again at the junction and the trail becomes a dirt path.
Once the vegetation to your right becomes more dense, watch out for a red ribbon and a trail that goes 45 degrees off to the coast.
Po Kwu Wan
The trail is narrow and slopes down towards the sea then turn right. You have to crawl under a weirdly grown mangrove tunnel before reaching the concrete bay.

It is kind of broken in places and the only way to go all the way across is to climb on to the railing, then there’s also a makeshift bridge towards the other end.
Because i was carrying a lot of electronics, we opt to go the same way back.
