Don your finest tailfin and dive into five days of mermaid magic in San Marcos. Taking place over the month of September, the annual Mermaid Splash event is packed with fun for all fishy friends. The event kicks off with a Mer-tini competition on Sept. 7 followed by a pair of symposiums on preserving art, culture and the environment. Sept. 20 brings the Art Ball, and you won’t want to miss the Mermaid Promenade and Aqua Faire the following day. The promenade features dancers and other performers alongside decked-out floats, and the free community faire afterward is full of delicious food, live music and art. Come celebrate the San Marcos River, the area’s culture and, of course, mermaids!
