While there’s never a bad time to visit SMTX, May is one of the best months for an art-filled and off-the-wall SMTXperience. Travelers searching for a quirky and colorful weekend adventure will love San Marcos’ local art scene, markets, and even a festival dedicated to mermaids! We are the Mermaid Capital of Texas after all…

Murals & More

One of the most important San Marcos cultural staples is the flourishing art scene. With an ever-growing collection of muralssculpturesgalleries, and more, San Marcos has created a thriving culture for art lovers and artists alike. From murals that take up the whole side of a building to teeny tiny pieces hiding in plain sight - you never know what you’ll find exploring San Marcos. New art seems to pop up in the most unexpected places. Next time you stroll around the Downtown Square we suggest taking a shortcut to look in alleyways and behind buildings to find your new favorite piece. Looking to keep the mermaid theme going? “Dive Into The Divine” (pictured above) can’t be missed as you drive into Downtown San Marcos. The beautiful mural is located on the back of The Coffee Bar building and depicts some of the local flora and fauna, as well as a striking San Marcos mermaid. The mural is a great place for a San Marcos selfie… Children's Park also has several mermaid selfie opportunities! And, of course, you can't miss the Mermaid March statues around town. Can you find them all?
