We took the nice scenic route till Oamaru, a picturesque town known as the Steampunk Capital.
After dinner we watched little blue penguins returning from their hunt on sea. Unfortunately, filming was not allowed.
But on the way back to our campground, we saw even more of those cute little fellas coming back to their nests. One nest was even within our campground.
