So many places, but what about the Far East? It would take a lifetime to explore China, and Japan is also a great place to visit (if you’re shy of “less developed” countries)
But I gotta recommend Vietnam too, I love the food and its so, so, so cheap (about 12p for a glass of beer, £4 to rent a 125cc bike for the day).
But then there’s also Thailand, Cambodia, Laos, Malaysia, Singapore nearby… you could visit all of them! All worthwhile. But China, too…. argh so much choice.
I went and visited Hong Kong (Which is also an AMAZING place) China, Vietnam, Cambodia, Thailand, Malaysia, Singapore last summer, in order to decide which I’d like to spend more time exploring, next time I go out East… I must say though, I loved every minute & I’ll have a hard time deciding, but that in itself is reason enough to go and visit them all (like me)!
And still I need to visit India and I’d like to see some of Africa too! Morocco is definitely on the list, though I’ve heard Fez is much cooler than Marrakech…
I don’t even know how you can ask this question! There is literally a whole world to explore, and literally all of it is amazing! Even the USA is amazing, once you leave their pitiable ideas of civilization & culture behind and go out into the wilderness! (Though obv NYC is on my list)
IME, if you want cities, things to see and do, to be able to casually stroll around all day, Singapore and Hong Kong will be great for you, but don’t forget there’s plenty to see and do in between!
