Founded in 1855 on the Llano River, the town became the county seat in 1856. By 1860, it was well established with stores, saloons and a hotel, but no church. The 1892 Llano courthouse has been restored to its original look. The downtown square has been designated a National Historic District, and Llano is now a Main Street town. The Lantex Theater, established in 1927, is a historic theater still showing first-run movies on a single screen. It also is home to the Llano Country Opry.
Llano is known as the "Deer Capital of Texas" and the Visitor Center hosts a Hunter Appreciation Event the first Friday in November to welcome the season's crowd. Year-round fishing in the Llano River and Highland Lakes area makes it popular with sportsmen. Rock hounds hunt for elusive "Lanite" or pan for gold in the Llano River.
Llano has kept much of its frontier charm, and is home to many world champion rodeo participants.
Camping and picnicking are available at all city and county parks. Some offer RV hookups, lake and pool swimming, fishing, boat ramps, hiking trails and scenic views. Black Rock and Shaw Island parks are on Lake Buchanan; Robinson City Park is on the Llano River; and the Llano County Community Center (park) and Llano Events Center covered arena are on the west edge of town.
