Grab tickets to watch a game at Trafalgar Park. If there's nothing happening while you're in the area, you might like to check if they offer a guided tour of the facilities.
You'll have to pay to enter this sporting facility, which is situated in Nelson. But there's lots more to explore around these parts than just Trafalgar Park. Christ Church Cathedral, Tahunanui Beach Reserve and Founders Park are also worth putting on your itinerary.
