The passenger-only ferry runs between Bluff and Oban up to four times daily (twice daily June to August). Book a few days ahead in summer (December to February). The crossing takes one hour and can be a rough ride. The company also runs a shuttle between Bluff and Invercargill (adult/child $28/14), with pickups and drop-offs.
Vehicles can be stored in a secure car park at Bluff for an additional cost (one/two/three/four/five days $21/31/41/52/62); there's also free unsecured parking opposite the wharf.
