Located in the heart of the Lower Rio Grande Valley, adjacent to   world famous Santa Ana National Wildlife Refuge, Casa Santa Ana is a beautiful   new Bed and Breakfast residence built specifically for birders and other   wildlife enthusiasts. CSA is nestled between the refuge and Military Highway   (Route 281), less than 200 yards north of the refuge and within an easy 10   minute walk of refuge headquarters. It features a detached guest wing, each room   with its own private bath, and a shared recreation room/kitchen with laundry and   entertainment facilities. Each room has an outside entrance. Owners Judy and   John McClung operate CSA as a "home stay" residence, meaning guests take their   meals and use the grounds and shared facilities in accordance with their   personal schedules and tastes. Because CSA is located "mid-valley," it is an   excellent jumping off point for other valley birding and recreation sites, from   Laguna Atascosa NWR some 45 miles to the east, to Falcon Dam about 75 miles to   the west. Just a third of a mile north of the Rio Grande River, it also is   minutes from shopping and sightseeing in Mexico. Perhaps most significant, it is   a quiet, private, secure retreat where guests can enjoy the unique environment   and wildlife of the lower valley while feeling very comfortably at home.
