The lakefront loop - Steamer Wharf, Earnslaw Park, Marine Parade past the gold-era cottages and into the Gardens - is an easy hour and costs nothing. Time it to the boats, the way I'd time a channel. The TSS Earnslaw, a coal-fired steamer from 1912, still crosses to Walter Peak with the engine room open to walk through; the basic cruise starts from NZ$129, and the evening sailing is quieter with better light.

From mid-May into late June she's on the slip and a modern catamaran covers the run - confirm the day's sailing, always. There's also the small bay ferry across to Kelvin Heights: about twenty minutes, hourly from mid-morning to late evening, ten dollars on a Bee Card. (I photograph timetables the way other people shoot sunsets. Judge me.)
