New Zealand
Drowned valleys folding whole seas of coastline into forested, road-shy waterways.
Ridges become islands and roads give way to jetties. The Marlborough Sounds are drowned river valleys — coastline measured in thousands of kilometres folded into a corner of the map — and whole bays here have done a century's business entirely by boat.
Queen Charlotte and Pelorus Sounds branch into hundreds of reaches around forested ridges, and the geography still runs on water: mail boats deliver to roadless bays, water taxis stitch tracks to lodges, and marine farms rope the channels — Havelock at Pelorus's head remains the green-lipped mussel capital in fact as well as title. The Queen Charlotte Track rides the ridgelines for some seventy kilometres, walkable in sections with launches linking the overnight stops — effort with a soft landing. The water rewards judgement: wind can rough up even enclosed-looking reaches, so paddling runs guided or forecast-first, and each visit picks one sound and a realistic mode rather than trying to drink the whole maze.
