The area immediately around Buffalo Gap contains some of the oldest live oak trees in Texas — several large specimens are credibly estimated at more than eight hundred years old, predating any European arrival in the region. The trees are scattered in private yards, ranch land, and small public spaces; the historic village preserves several within its grounds.
The oaks survived in part because the natural pass through the Callahan Divide here brought enough seasonal water to support them, where the surrounding plains could not. They are unmarked and unguided, but easy to spot — vast, twisted, low-spreading crowns of a kind you do not see north or east of here. A slow walk around the older streets of the village is the easiest way to encounter them.
