Celebrate Carnival in Houston at Carnival Houston Show and Parade. The event is back in Houston for its 3rd year with four days of entertainment, culture, costumes, and cuisine. The weekend kicks off with the Fantasy Costume Ball on Thursday. Friday night gets a little messy with a Neon Paint Rave including a body painting contest. On Saturday, 900 participants will flood the street with music, dance, floats, and costumes. After the parade, check out the Carnival Festival across from Discovery Green for food and fun. Bring the kids so they can check out the carnival rides.
