Why it's worth it: 

Some nice views but there's also a few other things to see and do on the island, such as the 19th century rock carvings, the Tung Lung Fort, and a few places to get a decent meal.

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

Yau Tong, Exit A2

Go down the stairs on the right, right out of exit A2. Then just keep following Cho Kwo Ling Rd road, all the way

Will take you about 10 minutes to get here from the MTR

Right after the last bend, the road straighten-up and the ferry pier as at the end 

You will have to get a return ticket. They will ask you for return time; you can pick the last return as you always have the option to take an earlier ferry back.

After a scenic 30 minutes ferry ride, you will arrive at Tung Lung island. It is the terminus, you can't get it wrong.

At the first cross-road, hang-out left.

Then right at the Chinese restaurant. (You will be looping back here)

Paved path for most of the trail, and there's one path so, quite easy to navigate

At this point, you will get to a fork. I suggest you first go explore the ancient rock carving on the right.
Once done, you will come back to this fork and keep progressing on the path on the left (2)

There's an explanatory sign on the middle of a promontory. The stairs down to the carvings are on the left.

Once done, retrace your steps to the fork and keep going

Luk Keng wan in sight.

You will get to this fork. If you feel like going to Luk Keng Wan, head right.
When done, come back here and keep going. You will be climbing to the summit; very painful on a hot day, easy otherwise.

Summit in sight

About 25m before arriving at the building, you will see a path on the left which you must take.
This is the way down from the summit. It is steep and slippery. If you are worried, trace your steps all the way back instead.

So, you have chosen to continue down the slope. There's a bit of bushwhacking but the path is quite clear and mostly follows underneath the electrical posts. 

The steep portion.

You made it all the way down!

You will reach this path, head right towards a small village where you can get a bit of food and drinks.
From there, you can follow the signs to visit Tung Long Fort (about 300m).

Once you are done, retrace your steps back to this village...

... and you can go back to the Public Pier by following the sign to 'Rock Carving' about 500m away.
