The average highs in September are 88 and the lows are 55 degrees Fahrenheit. The morning temperatures are just right for hiking, biking and exploring the park!
Definitely stop at the Canyonlands Island in the Sky Visitor Center and Needles Visitor Center when you first arrive at each park district. They are open every day in the September.
To photograph sunrise at Island in the Sky we like Grand View Point and Mesa Arch. And for the sunset we like the Colorado River Overlook.
Stargazing in Canyonlands in September
Canyonlands has the slogan: “Half the Park is After Dark”. Take the time spend one evening and LOOK UP! In September you can see the milky way right after sunset.
