Easy to do if you’re willing to do some serious hiking on the Big Island of Hawaii.

Actually the goal is to visit all seven with our son before he’s too old to want to travel with his parents. He’s 12, and we’ve spent pretty long vacations in Europe (England, France, and Italy), Australia (Sydney, Darwin, Cairns), Africa (Johannesburg, Capetown, Port Elizabeth, Hermanus, plus side trips to Zambia and Botswana), and Bali. I know, Bali doesn’t really count as Asia, so we really want to go to Japan as well. Planning a trip to Costa Rica next December, but unfortunately that probably doesn’t count for South America.
