Hong Kong caves at the Cape d'Aguilar

Are there caves in Hong Kong? With the mountainous region this small place has, one would assume there are some. I found a handful on my search through the interwebs, but most of them were not easily accessible, beach caves on islands that would require a boat trip, caves that can only be accessed from the sea, etc. However, the Cape d'Aguilar Marine Reserve hosts two wonderful caves that can be reached relatively easily. Both of these are beach caves.

To get to the marine reserve, one has to first get to the Shau Kei Wan train station, then take bus 9 to Windy Gap (not all bus nines stops at that though, see more detailed instructions here), and then walk four kilometers through the park to the reserve on the south end of the peninsula. We opted taking a taxi from my hotel in Hong Kong city center, all the way to Windy Gap. That is the easiest option, and not particularly expensive either (25-30€).

The walk from Windy Gap to the is very nice, along a gently sloping asphalt road among lush forests and hills. At the some point you hit some radio station areas, which you'll have to go around (don't go to fenced areas). Once past that point you will continue again on an asphalt road, until you arrive at the marine research building and the whale skeleton displayed in front of it.

Here's an overview of the marine reserve area, with the research building on the left.

And the whale:

Just before the marine research building there's a depression on the left, with a clearly visible large crack on the other side rock. This is the first, and more spectacular cave. It is a crack through the small hill, you enter from the land side/depression into the crack. The crack goes all the way to the sea on the other side of the hill, and waves crash inside the cave as well. Be careful, don't get drawn in the water by the waves!

A spectacular cave!

Then if you go around the research building, just behind the whale skeleton there's another cave, a rock arch. Also here the waves crash through the hole, be very careful here as well. Spectacular arch, but not as cave like as the other cave.

The crack cave, Cape d'Aguilar Sea Cave, is at N 22.208416 E 114.259597, and the arch cave, also Cape d'Aguilar Sea Cave, is at N 22.208037 E 114.260739.

I did this on the way in on my conference trip to China (flights were most convenient to Hong Kong), and on the way we managed to look (but not visit) at yet another cave, the Dragon Claw Cave. See the other article (alt. link).

After the cave excursion, I continued on the high-speed train to China's Shenzhen. The trains were wonderful, see below for a view of what kind of accommodation one needs for the the very long 12 minute trip. (Lower class tickets were sold out.)
