When we did South Amercia to Australia we stopped at Robison Crusoe Island, did NOT go ashore due to swells but they bought on the lobsters that are only found here and they were the BEST I have ever eaten. They grilled them on the deck and steamed them in Compass Rose. It was my DUTY to try them BOTH ways.
We stopped at Pitcairn but almost no ships land people there. It would have to be small ship that had zodiacs to get ashore safely. The people who lived there came on board and it was fascinating.
We were able to go ashore at Easter Island and that was a highlight of the trip. I heard we were VERY lucky usually it is not calm enough to land.
Raratonga again not able to be tendered ashore.
Not sure but it seems many of these smaller places in the South Pacific it is more likely you cannot land rather than can land. It may be why they dont do these places that do not have a lagoon or dock where they can get people off the ship. I have heard this request for the South Pacific so many times and they dont do it.
Has anyone ever researched to see if another line does this type of trip maybe from Australia that carries zodiacs so landings are possible? Marc there you go something for you to research.
