Rancho Lomitas is located on 177 acres of native Tamaulipan brushland in Starr County, Texas near Rio Grande City. When the ranch was purchased by Benito and Toni Trevino in 1986, much of the land and much of the brush was damaged by overgrazing. Since that time, Benito has dedicated himself to restoring the health of the brush and educating others regarding the importance of preserving this often overlooked but integral part of the local heritage and culture. As a result of landscaping with native plants near the main house, Benito has created a haven for Audubon's orioles, green jays, verdins, black-throated sparrows, and many other species associated with the thorny brush. Visitors can explore the flora and fauna of South Texas through the lens of local heritage and culture during Benito Trevino’s expert lectures on native plant use.

Several casitas are available for overnight stays, in addition to a small RV park available for overnight camping.
