Rio Oro Ranch is a fabulous live water property conveniently located just 10 minutes north of main street Boerne with a custom limestone ranch house that blends in seamlessly with the surrounding topography and overlooks a canvas of live oaks and native grassland sweeping down to the Cypress-lined Guadalupe River valley below.
The 6,500 sf headquarters, designed by renowned architect Craig McMahon and built by Billy Johnson, both Lake Flato alumns, has a total of 6 bedrooms and 6 bathrooms and is comprised of five buildings - main lodge, master suite, guest house, carport and barn - that are connected by breezeways and a central courtyard. The owners chose local materials for the construction of the house, including limestone and red oak, and wanted the footprint of the buildings to be one with the landscape. The builder and architect designed the house to be extremely efficient, installing a geothermal heating and cooling system coupled with natural breezeways off every room that cool the house 10 degrees with natural ventilation. The floor-to-ceilings windows in each room make you feel as if you’re living seamlessly within the surrounding nature. The focal point of the interior of the house is the gorgeous great-room with Douglas Fir walls and ceilings and a double-sided fireplace with a cozy study/TV room on the backside. The outdoor area is set up perfect for entertaining with the swimming pool, alfresco dining patio, grilling area, and pizza oven. Other improvements include a nice pole barn with attached shop, livestock barn, and large covered hay barn.
The highlight of Rio Oro Ranch is the 1.15mi of crystal clear Guadalupe River frontage which forms the SE boundary of the property. The diverse stretch of river ranges from steep canyon walls with deep pockets of water to shallow rapids easily accessible via a road down to a large gravel beach. There are 3 water wells on the ranch (1 windmill and 2 electric) which service the improvements and provide ample water for livestock and wildlife.
The terrain is mostly gently rolling / usable with elevations ranging from 1160-1320FASL. The owners have done a wonderful job clearing a large portion of the cedar allowing for native grasses to flourish and highlighting the myriad of Live Oaks scattered across the ranch. On the south side of the ranch there is approximately 50 acres of productive coastal fields along the river.
Native whitetail, turkey, hogs, free-ranging Axis, and more.
