Went for a short hike.
Was good, but unplanned and very hot: 2 piers on Lamma Island are completely isolated from each other save for 1 trail. No public transport unless you take a ferry back to HK Island and another ferry to the other pier.
Got bored on the south side so walked over to the north side. 1.5 hours, not bad, quite sunny, about 33°C…
