The Coromandel is another must-do, must-go place when you are in New Zealand. Especially when the weather is warm and you can’t resist the temptation to throw yourself into the cold, cold, sea for a refreshing swim! Well, the Coromandel is one of the warmest places in New Zealand so its a good bet. However you should beware that in the past the Coromandel has flooded from time to time, and people staying in tents are vulnerable to be washed away. So if you can arrange it, a cabin or bed and breakfast would be preferable. There are also a number of cottages available as holiday lets. If you take the time to plan in advance you arrange a holiday let before you get there. This tourism website has links to various accommodation options in the area. If you are thinking more long term, then you find rentals and real estate in the Coromandel here.
There are some good websites you can visit to see maps of the Coromandel and a video of the area. The Coromandel website also contains a current list of events scheduled for the area together with local markets.
