Aquarena Springs and Ralph the Swimming Pig

The Documentary of a Texas Treasure


The Magic of Aquarena Springs Comes to Life

My name is Bop Phillips and I grew up in San Marcos Texas.

I had the good fortune of working at Aquarena Springs Tourist Attraction from 1962 to 1972. It was a wonderful, magical place and those memories are still with me.

 It’s hard to find an American tourist attraction more legendary than Aquarena Springs, San Marcos, Texas. For a time, it was second only to the Alamo as the Lone Star state’s most popular destination. Where else could you see a pig swim with mermaids, or Glurpo the Clown smoke underwater?

The family-owned theme park, while no longer in existence, is still a vital memory for generations of Texans and out-of-state visitors.

The centerpiece was the “World’s Only Submarine Theater,” a marvel of engineering that would blow ballast and submerge an audience below the water. After it was opened in 1950, the submarine theater garnered wide attention — years later, we found it featured on the cover of a 1952 Popular Mechanics magazine (which also appears in the film).

Aquarena always had some new stunt to attract media interest — in the early 1950s it hosted the first underwater wedding, reported in Life magazine (to prevent the wedding gown from floating up over the bride’s face, small lead balls were sewn into the hem).

Aquarena’s greatest roadside triumph was the inclusion of a pig in every submarine theater performance. “Ralph” would run down the volcano ramp and execute a “swine dive” into the Springs, then swim, as the theater slowly submerged. The documentary provides all the details — the training and feeding, the special between-show retreat (“Ralph’s Pig Palace”).

This documentary tells the amazing story of one of America's most famous vintage roadside attractions, Aquarena Springs, located in San Marcos, Texas. Aquarena Springs was created post, World War II, and helped Americans change the way they vacationed. The construction of the interstate highway system, took people to the roads to see and experience the country at large. Aquarena was one of the first places in America to capitalize on this new tradition, and was a pioneer in what would become the modern amusement park and tourism experience. Aquarena hosted millions of Texas family members from, 1950 to 1996.  

The attraction was situated at the headwaters of the crystal clear San Marcos Springs. Aquarena Springs Resort,  with the world’s only submarine theater, aquamaids, Glurpo the underwater clown, glass bottom boats, Swiss Skyride, Texana Village (think Gunsmoke), and Ralph the swimming pig, was a state and national phenomenon throughout the second half of the 20th century.

Pictures from its attractions and underwater shows appeared in magazines and newspapers from Life Magazine and the Dallas Morning News to television programs like “What’s My Line?” and "On the Road with Charles Kuralt". After HemisFair, the 1968 World’s Fair in San Antonio, Texas the resort really started to become a household name.

When I heard that the new owner, Texas State University, was going to dismantle the entire park, I desperately wanted to keep the magical memories of Aquarena Springs alive. So over a period of 5 years, I collected vintage photographs and vintage footage and interviewed over 30 people who either worked at the park or visited it.

This documentary transports the viewer back in time. You will hear the nostalgic stories and see the amazing images of that magical place, called Aquarena Springs.

The documentary was a selection at the Thin Line Film Fest, an international documentary film festival.
