Walking further down towards the coast, we chanced upon the Chi Sun Correctional Institution. Of course our imaginations went haywire with gay prison fantasies. Alas, the facility has been closed - methinks due to the low prevalence of (prosecuted) crime in Hong Kong.
We weren't entirely sure how to proceed with the walk, and so it was fortunate that a ferry to Cheung Chau was just about to dock. We jumped into it - and onward to another island for a few more hours of make-it-as-you-go-along adventure.
