Fort Worth’s Fourth is an evening of FREE family activities, music and fireworks along the Trinity River at Panther Island Pavilion. Activities include live music, tubing on the Trinity River, bounce houses and much more. Don't forget to bring your blankets and lawn chairs for front row seats to Fort Worth's biggest firework display. Fort Worth’s Fourth 2013 will be a very special occasion. In honor of the 25th anniversary of the Fort Worth Sister Cities International partnership with the City of Nagoaka, Japan, the fireworks show will be one of the largest in the metroplex. They do fireworks BIG in Japan, so brace yourselves, they are bringing a little Japan to Fort Worth for a spectacular show packed with special effects like none other.
