Further south, the Texas Blackland Prairie stretches from Gainesville to Austin. Near Waco, the Brazos River valley offers scenic views. The Hill Country begins around Georgetown, with limestone bluffs and oak-juniper woodlands.

UNESCO World Heritage Sites

Additionally, the Frank Lloyd Wright-designed Price Tower in Bartlesville, OK (3 hours north) is on the tentative list.

Local Commerce & Culture

Ardmore, OK is known for the Greater Southwest Historical Museum. In Gainesville, TX, the Morton Museum tells the story of the region. Fort Worth has the Stockyards National Historic District with daily cattle drives. Waco is home to the famous Magnolia Market at the Silos. Gruene itself is a historic district with antique shops and live music at Gruene Hall.

The primary route is I-35 South, a well-maintained interstate with multiple lanes through most of the journey. Exits are frequent, with services every 10-15 miles. Gas stations are abundant, but prices vary. Fuel up in Oklahoma City (around $3.00/gal) before crossing into Texas where prices tend to be higher, especially near major cities.
