This is it, the last summer weekend to get out and explore Arizona and shake off the backyard dust. A change of scenery does the soul good!

We found three adventures that you might never think up on your own that will give you new insight into this big Grand Canyon State that we all call home.

You can thank us later.

Some of the fossilized wood in the Petrified Forest National Park near Holbrook dates back thousands of years.

Petrified Forest National Park

This one’s a bit of a haul. Head about 20 miles past Holbrook if you want to experience one of the world’s largest displays of petrified wood and historical structures. The park also has fossils that are 200 million years old — that’s old! — that tell the story of prehistoric earth and the people and critters who lived in Arizona’s Painted Desert.

You can hike along trails of a half-mile to three miles, camp in designated areas or take part in overnight backpacking/horse or mule treks.

There’s a charge to park — $20 good for seven days, or $10 for a motorcycle. If camping is not your thing you can drive 20 to 40 miles to the nearby towns of Winslow or Flagstaff to the north, Show Low or Pinetop-Lakeside to the south. The park is located at 1 Park Road near Holbrook, about a 4 1/2-hour drive from Tucson.

Hundreds of people participate in the annual Bisbee 1000 stair climb race every fall. You can get a jump on the competition by practicing over the long holiday weekend.

Bisbee

You know you want to take part in the 29th annual Bisbee 1000 — The Great Stair Climb on Oct. 19 — but you have no idea where to even start training.

Start at the bottom and climb up, one step at a time. You might not want to count off the steps because counting to 1,000 could wind you. But it also could be distressing around step 600 or so.

This holiday weekend is the perfect time to practice before the actual stair climb. And it’s the perfect excuse to get out of Tucson and up to the mile-high city of Bisbee where temperatures are at least 10 degrees cooler.

Here are a couple of other things to do while in Bisbee:

If you ever wanted to experience a day in a miner’s life try the Copper Queen Historic Mine Tour. Put on slickers, a mining hat, grab a lantern and travel 1,500 feet into the earth. Daily tours available. Call 520-432-2071 or go to queenminetour.com.

  • Grab a bite at the original Bisbee Breakfast Club on Erie Street in the gritty enclave of Lowell or do some day drinking at one of the bars or cafes in historic Old Bisbee where some of the buildings go back to the turn of the last century.

Bisbee is about a two-hour drive from Tucson.
