Discover the County
Williamson County
Williamson County was established in March 1848 and named for Robert McAlpin Williamson, a community leader and veteran of the Battle of San Jacinto. Georgetown became the county seat. The county’s physical setting crosses two contrasting regions: the rocky hills of the Edwards Plateau to the west and the Blackland Prairie to the east. That geography provides context for the communities that developed here. Today’s relationship with the broader Austin region is another layer within a county story that began long before modern metropolitan growth.
Berry Springs Park and Preserve provides a county-managed outdoor destination near Georgetown. Use the county’s current park information when checking access, facilities and any changes affecting a visit. A park outing can be combined with time in Georgetown, while Round Rock or other communities may fit better into a separate day. Public services also follow different boundaries, so distinguish county facilities from city parks and offices when looking for the information relevant to your plans.
What Shapes Us
Georgetown and Round Rock
The county seat and largest city are different places. Knowing their distinct roles helps when finding public information or arranging a visit around specific destinations.
Berry Springs
The county manages Berry Springs Park and Preserve near Georgetown. Consult its own visitor information for current access, facilities and the arrangements relevant to your outing.
Two Landscapes
The county spans Edwards Plateau terrain and Blackland Prairie. This contrast gives its western and eastern communities different geographic settings within the same county boundary.
Hill and prairie communities connect through shared Central Texas life.
