Hoi Ha loop (Marine park and Sai Kung West country park)

Appreciation: 6.5/10. Little bit boring. Some nice views still and a small beach. But it is so far away from everything; takes a while to get there... unless you live in Sai Kung. Note that there are boat tours that are available to you shall you decide to check out the corals that grow in the bay.

Why it's worth it: 

Duration: 

6k
50m elevation gain  (mostly flat)
Total: 2-3 hours 

Difficulty: 

3/10. 

Cel phone coverage: Everywhere. But watch-out for roaming.

Water needs: 1 liter.

Transportation: Minibus #7 from Saikung and back.

--------------------

Quite simple. Just a loop.

At the Sai Kung minibus terminus, just take #7 green minibus  which comes by about every 25-30 minutes.

After a 30 minutes ride, you'll arrive at Hoi Ha, a tiny village that does have a few restaurants. Go through the village. You will be heading right. There's only a single trail in that direction at that point.

Keep walking. Follow Wan Tsai directions.

To go towards Hoi Ha Marine Park...

... instead, go straight. From that point on, you can't really go wrong. You'll go by a first campground in about 100 meters or so. Then, about 3 km in, another one where the views are quite nice. Then you'll reach the end of the loop.
Make your way back to Hoi Ha.

--------------------

Off the Mui Wo ferry, head right, following the water.

Get to Silvermine beach

Towards Silvermine falls

About at Silvermine falls

Right at the modern gazebo.

Again right

You will get the trail markers for a while

At this point, is pretty much a single trail. Can't get lost.

Going by Discovery Bay

Intersection, go straight. Off the beaten path.

Disco Bay again, in the back.

Bushwacking. The path was still very obvious though. Rely on the Garmin map if it isn't.

About 3 or so hours in. Full-view of the land of Mickey.

Sunny Bay MTR in sight. Be careful on the way down.

Turn left, towards the uninhabited building

Right of it...

... through the gates.

Here, 2 options, if you head right, there's a tunnel underneath the highway. Head left (that's the path we took), you'll have to cross one section of the highway (just a one-way and there's not a lot of cars)

Green path on the right, blue path on the left. They merge on Sunny Bay road. Then do the little loop, under the  Noth Lantau highway, on you are there at Sunny Bay MTR.

--------------------

Refer to the numbered photos for reference to this map

Exit A2 at Tsing Yi MTR. That's leads you into the mall. Go through and go down one level. The mall exits right to the promenade. Head left.

Right after the Tsing Yi Northeast park. Just follow the Tam Kon Shan road for a little while. 

Be on the lookout after the public toilet on the right for the sign for Tsing Yi Nature trail that will be on the left. Head left.

The sign. There will be a bunch of steps. Not that many really.

The the tunnel that gets you under the highway.

Then right after, the paths split. Take the stairs.

About 10 minutes walk or so later, you'll reach the minibus bus terminal. Take the stairs on the right and head right on Lio To road. The road will curve to the left after about 200 meters.

End of pavement and Lio To. From that point on, it's all trails.

Head right.

Head right.

The path is new and quite nice. You'll go past a few gazebos and swings.

At this point, if you head left, that's the short way back to the North Entrance of the trail, where you came from. You want to head right towards the South Entrance.

Nice views of the bridge. Supposed to be really nice at sunset.

End of the trail proper. If you head left and walk and extra 150 meters, you'll reach the bus stop. Various buses will take you back to Tsing Yi. The two minibuses are probably your best option.
