 De Leon's party helped blaze the "Camino Real" (later known as the Old San Antonio Road), which followed present-day Hunter Road, Hopkins Street, and Aquarena Springs Drive (the route later shifted four miles to the south; it is now followed by County Road 266, known locally as Old Bastrop Highway).De Leon's party reached the river on April 25, the feast day of St. Mark the Evangelist; the river was thus named the San Marcos.In January 1808, a small group of Mexican families settled at the Old Bastrop Highway crossing of the river, and named the settlement Villa de San Marcos de Neve.
