Prosperous Port Lincoln, the 'Tuna Capital of the World', overlooks broad Boston Bay on the southern end of Eyre Peninsula. It's a raffish fishing town a long way from anywhere, but the vibe here is energetic (dare we say progressive!).
If not for a lack of fresh water, Port Lincoln might have become the South Australian capital. These days it's salt water (and the tuna therein) that keeps the town ticking. The grassy foreshore is a busy promenade, and there are some good pubs, eateries and aquatic activities here to keep you out of trouble.
