Ashton Kutcher and Mila Kunis are staying true to their low-key style as they went on a rustic honeymoon following their surprise wedding over the weekend. 

According to Entertainment Tonight, the newlyweds drove off in an RV after saying their wedding vows at the Secret Garden in Parrish Ranch in Oak Glen, California on Saturday, July 4, to celebrate their honeymoon in Yosemite National Park. The two, along with their 9-month old daughter Wyatt Isabelle, were reportedly spotted by a Twitter user checking into the historical Ahwahnee Hotel. The lodge, which dates back to 1927, boasts views of several popular attractions in the area including the Half Dome, Glacier Point, and the Yosemite Falls. 

One observer, who posted pictures of the family on Twitter, saw Kunis and Kutcher during lunch, and the actor was wearing a white shirt, a black baseball cap, and his wedding ring. Kunis was also casually garbed in a blue tank top, shorts, and sneakers. 

At one point, the family reportedly went to an open field where the 9-month old practiced walking while her father held her hands and Kunis encouraged her with a big smile. 

When approached for pictures, Twitter user Ellie Byrd said that the couple politely declined but Kutcher did offer a handshake.

The couple's wedding was similarly rustic as it was reported that guests were offered luxury tents to stay in and "Camp KuKu" signs were placed all around the venue. According to People magazine, the secret wedding was more of a low-key celebratory party, as Kunis and Kutcher have already gotten legally married before the event.

Kunis and Kutcher were together on the set of "That 70's Show" from its 1998 premiere to its 2006 conclusion, but didn't start dating until 2012. They got engaged in 2014, and Kunis gave birth to their daughter in October.
