Zac Efron took full advantage of all Oahu, Hawaii’s outdoors had to offer on Sunday.

“Cowabunga,” Zac Efron said in an Instagram video post.

“Aloha,” Efron posted with another Instagram photo of himself maneuvering a tire swing attached to a rope that was tied around a tree branch over a pond while DeVine flexes in the background.

Efron, the former “Hairspray,” “High School Musical 3: Senior Year,” and "17 Again” actor, shared the excursion with Aubrey Plaza and Adam DeVine, whom he will join in acting out roles for the comedy “Mike and Dave Need Wedding Dates” – due in theaters July 8, 2016.

You can also see him in “We Are Your Friends,” when it hits the big screen Aug. 28, 2015, imdb.com reported.

"Here's to me being way more muscular and generally more shredded than my lil bro @zacefron," DeVine said in a post on his Instagram account. "In our off time we jump off waterfall's and nearly escape death. Nbd. Having so much fun shooting #mikeanddaveneedweddingdatesthis summer in Hawaii!"
