One of the biggest draws in Port Neches is the four-day Riverfest held in May. Sponsored by the Chamber of Commerce, this festival, held at Port Neches Park, is a fun-filled family event. Riverfest wouldn’t be a festival without the Mighty Thomas Carnival, the delicious foods and arts & crafts vendors, live musical entertainment, parade, a fabulous fireworks display, talent show, and the various tournaments and contest that are held in conjunction with it.
