Auckland, New Zealand’s largest city, has many things going for it. It’s home to the world’s largest Polynesian population. It’s built on an active basaltic volcanic field – the only such city in the world. It’s got great museums, the southern hemisphere’s largest marina, and a fabulous aquarium. Still, there’s a lot to appreciate outside the city limits. Great black sand beaches and rainforests are easily accessible on day trips from Auckland. You can also drift down an underground river illuminated by glow worms. Oh, the scenery outside of Auckland is pretty spectacular, too.
