Pets are permitted in very limited areas of Lyndon B. Johnson National Historical Park. They must be kept on a leash no longer than six feet at all times. Pets are NOT allowed in park buildings.
Do not leave pets unattended in vehicles. Interior temperatures of vehicles can soar above 120°F (49°C) in minutes. Pets can quickly overheat and die under these conditions, even with the windows cracked.
Lyndon B. Johnson State Park and Historic Site does allow leashed pets on trails.
