We had a late-afternoon, direct flight out of Auckland back to California (into SFO not San Jose but close enough!) So we could do one thing in Auckland, just one thing...
Go see a volcano (of course-duh!)
From Mount Eden you get spectacular 360 degree views of Auckland.
It is the highest natural elevation in the city.
I would also recommend visiting the Sky Tower (I did that last time.)
It had been an amazing trip. Even better this time round, sharing it with My Husband. Alas, it was time to go back to our home in San Jose where the garden was waiting impatiently for us, having been very busy during the rainy season while we were gone.
