The Hagen Trail at Red Rock Canyon State Park travels past red-stained sandstone curtains, rock windows, and desert cliffs. Well over 100 movies have been filmed in Red Rock Canyon State Park, including westerns such as "Zorro Rides Again", "The Big Country", and "Law and Order" starring Ronald Reagan, as well as other hits such as "The Ten Commandments", "Jurassic Park", and "Beneath the Planet of the Apes". Although the main trail is only 1.1 miles long (with a 0.1 mile side trail to a bench), it is possible to spend several hours in this area exploring red cliffs, washes, and side canyons just off the main trail. Off-trail exploration is allowed, as many of the points of interest are several hundred feet off the trail. Be sure to be careful off trail, especially on uneven ground, as much of the rock is sandy, weak, and can easily crumble if weighted.
