- Rule
Landing depends on the swell
1 Jan – 31 DecClosuresEverything and everyone comes ashore by longboat through the surf at Bounty Bay. When the swell is up the captain calls it off, and a scheduled visit becomes a slow lap of the island from the rail. Source ↗
- Rule
Quarterly ship from Mangareva
1 Jan – 31 DecBook earlyThe MV Silver Supporter is the only scheduled way in, running in quarterly blocks from Mangareva in French Polynesia and timed to the weekly Air Tahiti flight. Twelve berths, so dates are taken a long way ahead. Source ↗
- Holiday
Bounty Day
23 JanNational holidayClosuresEvery 23 January the island burns a model of the Bounty in the bay, the way the mutineers burned the real one in 1790. Almost everyone here is descended from the men who lit it, so it is a family anniversary as much as a public holiday. Source ↗

Cruise ship days
1 Oct – 31 Mar · usuallyCruise seasonCrowdedA handful of ships a year anchor off for a few hours, mostly in the southern summer, and the whole island comes down to the square to sell carvings and honey. Between calls Adamstown sees almost nobody. Source ↗
