DivinylsFan I know it's easy to get to visa level 3, which is why I haven't done all the adventures. I don't generally grind enough to accomplish it in one trip though, and I space out the trips, so it takes a while for my sims to actually get there.
The grapes (I meant cranerlet nuala and gralladina fran, only available at visal level 3) do grow in the basement of the Landgraab estate, and probably at the abandoned house too, although I haven't checked there in a while. But there are only a few plants each, and my sims want to make nectar while they're waiting for their crops to mature, so collecting a large quantity at once is much more convenient. Not to mention, my sims sleep overnight on the island and get another pass through Tuatha's Garden the next day without having to travel over there again.
My understanding is the island is only accessible by swimming (which takes a very long time) or Zeneport (which means time spent building the Martial Arts skill and meditating), so it's not any better from an efficiency perspective. And this way, they get treasure along with enough grapes to last until one of them can plant and harvest the rare grapes at home.
@puzzleaddict there are a lot of grapes to be found in that tomb near the little fishing hole. You just need Pangu's Axe to get to it.
