Confluence Park
Twenty-eight cantilevered concrete "petals" — engineered by Lake|Flato and California firm Matsys using plant-frond biomimicry — fan out over a former industrial laydown yard, funneling rainwater into a hidden 100,000-gallon underground cistern that captures roughly 825,000 gallons a year.
-
Bracken Cave Preserve
At dusk, up to 20 million Mexican free-tailed bats spiral out of the cave in a mile-long living column — the largest known concentration of mammals on Earth — on a preserve of roughly 1,500 acres in southern Comal County near Garden Ridge, managed by Bat Conservation International, a short drive northeast of downtown San Antonio.
-
The Ghost Tracks
For decades, drivers parked in neutral on these tracks and felt their cars roll forward, 'pushed' by the ghosts of children supposedly killed when a school bus stalled and was hit by a train -- an accident that Snopes traces to 1938 Utah, not Texas. In 2018 Union Pacific regraded the crossing specifically to kill the illusion, but people still detour here to test it.

Dionicio Rodríguez's Faux-Bois Bridge & Torii Gate, Brackenridge Park
A pedestrian bridge that looks assembled from gnarled tree limbs, complete with fake bark, knotholes, and broken branch stubs, is actually cast concrete — one of Mexican folk artist Dionicio Rodríguez's 1920s "faux bois" illusions, done with the same trompe-l'oeil technique he used on the garden's torii-style entrance gate.
-
Miraflores Park
A forgotten 1920s private garden built by Dr. Aureliano Urrutia, a surgeon who fled the Mexican Revolution, modeled on his native Xochimilco — faux-bois "wood" gates, a covered bench, and a grotto poured entirely from tinted concrete by Dionicio Rodríguez, plus a life-size statue of the doctor and a Winged Victory replica.
