Zac Efron is soarin’, flyin’ through summer.

The High School Musical alum shared a rare glimpse into his private life, posting photos and videos from a recent trip to California’s Lake Nacimiento with his younger brother Dylan Efron.

One snapshot posted to Instagram Sept. 10 showed the siblings baring their washboard abs on the back of a boat, while Zac, 38, rode the waves on a small surfboard in another image. In a third photo, the Iron Claw star and Dylan, 34, soaked up the sun with friends.

While Zac captioned his post with a peace sign emoji, Dylan—who shared similar pictures from the lake getaway—wrote on his own Instagram, “Taking it easy.”

Indeed, Zac has been breaking free away from spotlight, making just a handful of public appearances in recent years. That’s why when he made his long-awaited entry into the Dancing With the Stars ballroom in November to support his brother, it “meant everything” to Dylan.
