Missions, springs, river towns, and brush country
San Antonio is the big front door, but the wider region runs through mission country, old immigrant settlements, spring-fed rivers, ranch towns, military history, and communities where the Hill Country starts giving way to South Texas brush.
These are Texas Porch browsing regions, not legal or scientific boundaries. Natural regions, water systems, counties, and official heritage trails overlap them. That overlap is part of the story.
Read the region
Landscape, water, and human history do not share one border. These three threads are a better first read than a list of city names.
Water underfoot
TWDB explains that the Edwards Aquifer runs through faulted, cavernous limestone. Springs make that hidden water visible, and the system can react quickly to rain, drought, recharge, and pumping. That is why aquifer questions show up in ordinary local life.

The Texas Historical Commission's San Antonio route joins Spanish missions with Canary Island settlement, Tejano history, markets, parks, and later neighborhoods. The region's history is still visible in working civic places, not only behind museum glass.

Spring-fed rivers and creeks cross several landscapes in the San Antonio flood-planning region. The practical habit is simple: enjoy the water, but read the forecast, crossings, and parcel-level flood information as part of the same outing or property check.

Official sources for the regional frame
Texas Porch uses these statewide sources to explain the landscape, groundwater map, and heritage regions. Individual place spotlights link to their own source above.
Before you act: Regional patterns are orientation, not parcel-level answers. Confirm the local utility, district, office, permit, forecast, or access page before a decision. How to use Texas Porch carefully.
