Only in New Zealand, only at Hot Water Beach: Build your own hot water pool with a small shovel. But not every spot works. We had dug a beautiful little pool for ourselves, it just wasn´t hot. So we retried a couple of meters to the left and voilà! Our own little spa. Oh, and make sure you come during low-tide, otherwise you can´t reach the hot spots. And be there early enough, too, otherwise all the good spots are taken!
