There’s nothing more fun than a trip to the beach in the summer. But costs can add up. Got Galveston in your travel plans? Here are three free things to do.Tree sculpture tourAfter Hurricane Ike ravaged Galveston in 2008, a group of Galveston homeowners decided to band together and turn the devastation into art. As you travel the island, look for its incredible tree sculptures, which range from the historical (a replica of the figurehead from the island’s famous Tall Ship Elissa) to the whimsical (a pod of dolphins with a mermaid). Kids will appreciate recognizable items such as a guitar, a squirrel and even SpongeBob SquarePants. Find a list of sculpture addresses online at galveston.com/treesculpturetour — many are centered in the city’s East End Historic District — then take a free driving tour. Taffy demonstration at La King’s ConfectioneryLa King’s Confectionery dates back to 1927, when Jimmy King learned how to make “Old World” candy in Houston. In 1976, his son, Jack, moved to Galveston and recreated an old-fashioned confectionery in the historic Strand District. In summer, it’s a must-visit destination thanks to its working 1920s soda fountain, delicious handcrafted shakes, rainbow rows of candy and saltwater taffy, which you can watch being pulled and stretched in store most Wednesday through Sundays. During a free hourlong taffy-making demonstration, made using antique equipment, guests receive samples. Call 409-762-6100 or visit lakingsconfectionery.com for more information. Movie night on the StrandNo visit to Galveston is complete without spending some time in the historic Strand District, which is filled with shops, museums and restaurants. After a fun-filled day exploring the area, head to Saegerfest Park, which hosts Movie Nights and Music Nights many Saturdays in summer. It’s a great excuse to grab a blanket or some lawn chairs and take in a free family-friendly flick or concert. Visit galveston.com/saengerfestpark for more information.
