The beach is on the north side of the island, giving it the best sun exposure (remember, southern hemisphere!).
Onetangi Beach is part of Waiheke Island, eleven miles northeast of Auckland - a great side trip on a sunny day. This was only our second day in New Zealand and we'd been extremely busy on our first day, but we were up and out in time to catch the morning ferry.
It was rather exciting to watch the skyline recede - as interesting as a city can be, I am exposed to urban life on a daily basis, and I was ready to see something a little different! After about a 40-minute ride the ferry dropped us off on the island and we hopped on a bus tour, since there were limited options for seeing the island. We'd hoped to go wine tasting but settled for beer and fish and chips on a deck overlooking another bay.
The Matiatia Malt by the Waiheke Brewery was the best beer of my entire visit, due only partly to the setting!
