Amarillo: Cadillacs planted in the Texas desert

Along historic Route 66, Amarillo preserves ten Cadillac cars buried upside down in the earth, one of America's most photographed public art installations.

A car remains necessary to reach the attractions scattered outside the city.

Cadillac Ranch, ten vintage Cadillacs planted upside-down in a field, invites visitors to decorate them with spray paint, continuously changing their appearance.

Minutes away, a stretch of the historic Route 66 passes through Amarillo with neon signs and period diners still operating.

In the afternoon, one should venture to Palo Duro Canyon, North America's second-largest canyon after the Grand Canyon, with red and orange rocky walls.

As evening falls, an Amarillo restaurant proposes the challenge of a nearly one-kilogram steak served free to anyone who finishes it within an hour, now a historic Texas tradition.

Cadillac Ranch, installed in 1974 by an art collective, changes appearance daily thanks to thousands of visitors who leave their mark with spray paint in an art installation never truly concluded.

Palo Duro Canyon, carved by the Red River over millions of years, displays layers of colorful rock that tell the story of hundreds of millions of years of geological history.
