Zac Efron is currently in Hawaii filming the upcoming comedy 'Mike and Dave Need Wedding Dates' alongside co-star Adam Devine.

When they are not busy on set, they took advantage of all the island has to offer.

In between filming scenes, Efron has been channeling his inner Tarzan hiking, swimming with sharks and rope swinging into a scenic pool of water.

Last month, he was spotted on a hike with his co-stars, actress Anna Kendrick and Aubrey Plaza. The trio decided to get a little exercise by climbing Oahu's Lanikai Pillbox Trail.

Over the weekend, he went to a lake in Oahu with Devine to have some fun in the sun. Zac took to Instagram to document his adventure with his co-star to a local lake where they stumbled upon a tire swing and just had a blast.

He posted a steamy snap of him flexing his muscles while Adam posed while balancing on the large tire, captioning the shot "Aloha."

Adam uploaded a photo of the duo showing off their ripped muscles as they posed casually on a rock.

He captioned the snap: "Heres to me being way more muscular and generally more shredded than my lil bro @zacefron. In our off time we jump off waterfall's and nearly escape death. Nbd. Having so much fun shooting #mikeanddaveneedweddingdates this summer in Hawaii!"

Zac shared a slow motion clip showing off his swinging skills before being submerged under water.

The 'High School Musical' star also shared an awesome snap of himself swimming with the sharks. It was his second time out with the sharks, on June 8 he uploaded a photo of him reaching out to touch one of the sharks. 

Mike And Dave Need Wedding Dates follows two brothers who buy personal ads to find a pair of dates to be their guests at a wedding. The film is scheduled for release in US theaters on July 8, 2016.
