50 Free Things to Do in Metro Phoenix Any Time in 2017

Low on funds and high on FOMO? We can help with that.

Phoenix is rife with no-cost events worth freeing your schedule for, including trivia nights, open mics, parks, bike rides, and a good deal of art walks. Because saving money is always in season, here are 50 free things you can do all year round.

It's a book club with a sudsy twist. The Phoenix location of Changing Hands Bookstore holds a once-a-month meetup of bookish minds at the First Draft Book Club, hosted by The Arizona Republic's Barbara VanDenburgh. Expect to nerd out about a chosen book each month alongside brews, wine, and coffee at the First Draft Book Bar. For details, visit the Changing Hands website, or call 602-274-0067.

Tease Your Mind
Crescent Ballroom keeps the downtown music scene going day-to-day, but on Sundays things unwind with trivia and DJ Heimbuck at the helm. Starting at 6 p.m., brainiacs can put their smarts to the test in exchange for such prizes as concert tickets, record store gift cards, and more. Visit the Crescent Ballroom website, or call 602-716-2222 for details.

Strike a Pose
The clothes may not be cheap, but the community yoga classes are. Every Sunday, the Lululemon stores in Phoenix, Scottsdale, and Chandler host complimentary yoga classes. These free classes are held in or outside the store, depending on the weather. Guests should bring their own mats and water. The Biltmore Fashion Park and Scottsdale Quarter classes start at 10:30 a.m., and the Chandler Fashion Center class begins at 8 a.m. For details, visit the lululemon athletica Phoenix Facebook page.

Yuk it Up
Prepare to laugh (or cringe) as local comedians take the stage at ThirdSpace's free, weekly Happier Hour Comedy Show. Each Thursday from 7:30 to 10:30 p.m. you can spot up-and-coming talent.

Get Blinded By Neon
Take a self-guided tour through the blinding lights. The Valley's dwindling neon sign population proves only the strong survive. In fact, some preservationists estimate that a mere three dozen of the vintage illuminated displays exist in metro Phoenix today. Hippie Gypsy in Tempe, Lenny's Burger Shop in Phoenix, and Liberty Market in Gilbert still keep the glowing tradition of neon alive, and there are even more you'll find in our guide to the best neon signs in metro Phoenix.

Live that Lake Life
Tempe Town Lake is Tempe's recreational center. Bike by Tempe Beach Park, take a stroll down the length of the lake, practice your photography skills at the bridge, or just do some seriously great people-watching. If you're feeling spendy, you can rent a stand-up paddleboard for $20 an hour, a single kayak for $18 an hour, or just save your money and take a dip in the lake. (Just kidding! The water is really gross.) It's also a good spot for Pokémon Go — if you're into that sort of thing. Visit the City of Tempe website for more information.

Keep your quarters in your pocket every Monday night at Valley Bar, where all games are free starting at 6 p.m.. Perfect your Skee-Ball game, shoot some pool, or show that Teenage Mutant Ninja Turtles video game who's boss. It's all good, and it's all free. Visit the Valley Bar website, or call 602-368-3121 for details.

Get Fresh
Even if you don't want to spend cash, Valley farmers markets are a great way to mix and mingle with local farmers, merchants, and artists. These markets tend to dodge the summer temperatures by either closing during the hot months or opening extra early to get a jump on the heat. (Some even move indoors.) Get the full lowdown on our list of metro Phoenix farmers markets — all free to drop by.

Table Top Game Night
Mesa's The Grid: Games and Growlers hosts a weekly Table Top Game Night on Thursdays.

"Check Out" Local Culture
Phoenix, Chandler, Glendale, Scottsdale, and ASU libraries all offer a Culture Pass, with which library card holders can get free admission to some of the Valley's most revered cultural institutions. Notable locations include the Desert Botanical Garden, Phoenix Art Museum, Heard Museum, Scottsdale Museum of Contemporary Art, and more. Check your local library's website for availability.

Catch the Classics
It's no Barrett-Jackson, but the Scottsdale Pavilions Car Show is likely the best local car show you can see for free every week. The longest-running weekly car show in the country draws crowds from 4 to 11 p.m. every Saturday, and the public is welcome to drive their classic, muscle, or luxury car onto the lot for a chance to show off. The every-Saturday event sees anywhere between 250 and 500 cars. Visit the Scottsdale Pavilions Car Show Facebook page for more information. And as fate has it, more than 35 food trucks roll onto the lot at Scottsdale Pavilions to stop rumbling bellies at the same time each week. (But not rumbling cars.)

Get to Work
If you're in town for business or just need a quiet place to work, Gangplank locations in Chandler, Avondale, and Queen Creek offer a free co-working space to anyone who drops by. Use the Wi-Fi, make some business connections, and enjoy a free space to work just for a day, or day-to-day. While Gangplank doesn't charge money for its space, it does ask that regular visitors give back in some way, but how you give back is up to you. Visit the Gangplank website for locations and more information.

Ghosts Among Us
Back in the 1890s, Goldfield, located 4.5 miles east of Apache Junction, was a thriving town with roots in mining the Mammoth Gold Mine. But when the vein faulted, so did the town, leaving the three saloons, a general store, brewery, meat market, schoolhouse, and more abandoned. Today, it's a great place to take out-of-towners looking for authentic history of the Southwest. It's free to enter and to see the hourly gun shows every Saturday and Sunday, but just about everything else will cost ya. Visit the Goldfield Ghost Town website for more information.

Free Association

Find Your Heritage
You've probably heard that Phoenix doesn't have much in terms of history, since Arizona is such a young state, but tell that to Downtown Phoenix's Heritage Square. Originally constructed in the late 1800s, the square is like traveling back in time. Check out the square's free seasonal events, or if you have some spare cash, we hear there are some pretty good (a.k.a. nationally revered) restaurants in the area. Visit the Heritage Square website for more information.

The Bat Cave
Phoenix has some great urban bat-watching areas, the most impressive of which is the Maricopa County Flood Control Tunnel (a.k.a. the Bat Canal) in Arcadia near 40th Street and Camelback Road. From May through October, a couple thousand Mexican free-tailed and western pipistrelle bats exit the tunnel at sunset. They start as a trickle — and grow to resemble an all-out cloud of bats. Just be sure to whisper, and do not use flash photography. Visit the Arizona Game and Fish Department website for more information.
