Staying Wild! Reese Witherspoon Takes Son Deacon on Hiking Trip

07/20/2016 at 02:05 PM ET

Reese Witherspoon may have already gotten an Oscar nod for her portrayal as protagonist Cheryl Strayed in Wild, but she hasn’t left her wilderness-friendly days behind her — in fact, she’s taking her family along for the ride.

On Tuesday, the mom of three shared an Instagram selfie that included her 12-year-old son Deacon. In the background? Tents, an expanse of trees and pretty much nothing else.

“Let’s do this! Into the wilderness we go,” Witherspoon, 40, captioned the shot.

The Legally Blonde icon also added the hashtags, “#StayWILD” and #HikingTrip.”

The New Orleans native — who, along with Deacon, is mom to 16-year-old lookalike daughter Ava with ex-husband Ryan Phillippe, as well as 3½-year-old son Tennessee James with husband Jim Toth — shared more glimpses into the twosome’s trip, including a video of horses hanging out next to a beautiful stream.

Witherspoon also included a simple shot of her hiking boots alongside an inspiring message encouraging her followers to join along in the great outdoors.

“That first step into nature. Who else is out there hiking and exploring the world!?” she wrote. “Share your adventures, or favorite nature quotes, as I share mine. Embark on this adventure with me by using #StayWILD.”

Enjoying the great outdoors 😍🌲🏔🐴💚 #HikingTrip

The mother-son getaway comes about a month after Deacon’s elementary school graduation, where the actress and businesswoman showed off her pride for her middle child on Instagram and Snapchat.

“Off to Jr High! Yay, Deacon! #proudmom,” Witherspoon captioned a memorable shot.

LOL into the “wild”? Um, that’s called GLAMPING. Not exactly roughin’ it. And I notice selfie-queen Reese who has become annoyingly narcisstic (I used to like her … ) has perfect eyeliner and lipstick, and perfectly mussed and styled hair. Yeah … not exactly “wild”.

Tents, trees, and an Instagram selfie … snort.

There’s a bed in the tent!

Laughing at how she tried to keep the permanent buildings in the background out of the frame. Those are glamping tents she stayed in; that’s not roughing it. It’s like sleeping on the balcony of your hotel room lmao

With the way I sweat,if I wore all that makeup while hiking I believe everyone would run off the trail in horror.
