Monday's walk was one of those 'it's the journey, not the destination' outings. In theory I was going to find the location of pillbox 72, but in any case it was lovely weather, and a good excuse to scramble over some rocks.

The map we've been using shows pillbox 72 on the coastline, somewhere between Jubilee Battery and Kennedy Town. Last weekend we took a ferry to Lamma, so I used the chance to take some photos of this section of the coastline. It's the view as you pass through Sulphur Channel, between HK Island and Green Island.

I'd love to see some of the old buildings that have long ago been demolished - be able to look all around them, and get in close to see details. Which one would you choose?

Last week we introduced the new Places feature. They help you find your way to a place in Hong Kong.

That's great if you know where you want to get to. But what if you've just got a vague idea? eg 'I expect to be working in Central, which serviced apartments are nearby?'. Or "I'm staying in a hotel on Nathan Road, any friendly pubs nearby?".

Join us on a walk around Hospital Hill in Wanchai, looking for signs of the air-raid tunnel network that was dug under this hill. The hill is currently the site of the Ruttonjee Hospital, but at the time of the second world war you’d have found the Royal Naval Hospital located here.

You probably know the stone steps of Pottinger Street in Central, but how did it get its name, and what happened to its tunnel?
