Kirk Douglas is still enjoying the great outdoors!

The 102-year-old Hollywood icon was photographed resting on an air mattress inside of a green tent, which appeared to be set up in a backyard, on Friday.

His grandson, Cameron, 40, shared the photo on his Instagram account, writing, “This amazing man, my Pappy, is such inspiration in so many ways! Going camping at 102! #Spartacus#thrunthru 📸@Lisa.”

The three-time Oscar nominee turned 102 on Dec. 9, which was celebrated by his large family, including his son Michael and daughter-in-law Catherine Zeta-Jones.

The actress shared a sentimental tribute to her famous father-in-law in an Instagram post, in which she shared photos of Kirk’s life and career.

“Happy 102nd birthday to the most beautiful man,” Zeta-Jones captioned the post. “We love you Kirk.”

Her daughter, Carys, also wished Kirk a happy birthday, posting a throwback of her grandfather and father, Michael, together. “102 years young to my inspiration, my pappy,” she wrote in the caption. “I can’t put into words how much you mean to me. Happy birthday, I love you.”

As Kirk grows older, he is not missing a beat. In November, Michael, 74, revealed on Live with Kelly and Ryan that Kirk has picked up FaceTime.

“He’s amazing. He’s discovered FaceTime. He just loves it,” he said.

And in December, Michael told PEOPLE that Kirk remains skilled at betting on sports games.

“He beats me all the time,” said the actor, who nabbed a 2019 Golden Globe nomination for his work in The Kominsky Method. “The last bet I made with him was for $100 on a Jets game — and I lost.”

“I’m a big sports junkie and my father knows nothing about [the games],” Michael added. “I can pick any team and he’ll just take the other one … and [yet] he cleans my clock.”

When Michael received his star on the Hollywood Walk of Fame in November, Kirk was sure to attend — and he received a special shout-out from Michael in return.

“It means so much to me, Dad, that you’re here today,” Michael said in his speech. “Thank you for your advice, inspiration, and I’ll say it simply and with all my heart: I’m so proud to be your son.”

“Seeing Kirk get emotional when Michael said, ‘I’m so proud to be your son, Dad’ — even now I think about it,” Zeta-Jones told PEOPLE Now later in November. “Kirk being there in his wheelchair — he was adamant. No way he was not going to be there.”
