Offering a unique blend of historic charm and modern potential, this estate is a rare opportunity for ranchers, developers, or those seeking a tranquil retreat. Spring Oak Farms is a sprawling 133 acre farm & ranch with distinctive topography features that will leave you speechless. Generations of stewardship have preserved the land's character and diverse terrain to include stunning views, rolling hills and lush woodlands. The American Colonial Farmhouse highlights early 20th-century charm and boasts over 5000 square feet, 4 bedrooms, 5 full baths, front and rear staircases, multiple living and dining areas. Additional structures such as a guest house, cottage, outbuilding, log cabin, an event center and private chapel accentuate the vast possibilities of the property. Both barn-style event center and picturesque white chapel were recently constructed in 2020 and exude vintage charm with nostalgic interior elements like reclaimed wood, vintage doors, and vaulted beamed ceilings. Although the ranch is draped in Texas Hill Country appeal, it's conveniently located 5 minutes away from downtown San Marcos or Texas State campus. It's walking distance to pristine, spring-fed San Marcos River and the Aquarena Springs Nature Center. San Marcos sits 45 mins south of Austin Metro market and 45 mins north of San Antonio. The property also boasts two State of Texas issued designations and was once the epicenter of thriving River Head Farms. Sink Creek, a direct window into Edward's Aquifer, and many other natural areas are yet to be discovered on this beautiful terrain. Spring Oak Farms is prime for a wedding venue, retreat center, hunting ranch, or a personal family compound. However, with ample space for expansion, this property offers possibilities for eco-tourism, ranchers, residential development, or potentially mixed-use development. Tour Spring Oak Farms and let your imagination soar.
