It's been six years since actor Paul Walker's tragic death, but those close to him still remember him often.

The late actor's daughter, Meadow Walker, 20, shared a sweet tribute of her father on Saturday. In the photo she posted, the actor smiles while swimming in the ocean with a pig.

She added a simple yet loving caption to the shot: "thinking of you xx."

Many friends of Meadow left emotional and supportive comments on the post.

Jordana Brewster, the late actor's "Fast and the Furious" co-star, wrote, "I love this picture 💗," to which Meadow responded, "me too! & I love you."

Tyrese Gibson, another co-star of Walker's, wrote, "Animal and Ocean lover!!! Never seen this pic! So cool!"

Meadow launched the Paul Walker Foundation in 2015 to carry on her father's legacy. In her post announcing the organization, she explained its significance.

"Reflecting on my father, I found myself reflecting on his passions," she wrote in an Instagram post. "His passion for the ocean, his passion for rescuing animals, his passion for helping people and his passion for spontaneous goodwill. I wanted to start this foundation because I want to share that piece of him with the world."

"I want to share that part of him with others," she added.
