Purchase a ticket and join the fans at a game at Harlingen Soccer Complex. If there's nothing scheduled while you're in town, you might like to check if they give a guided tour of the grounds.
This sporting facility is on the to-do lists of many visitors to Harlingen. But Harlingen Soccer Complex isn't the only drawcard in the area. Treasure Hills Golf Club, Iwo Jima Monument, and Museums of San Benito are some other recommended attractions close by.
