Back to where it all started!

Amy Duggar and her husband Dillon King celebrated their first wedding anniversary by returning to the place they spent their honeymoon — Cancun! But the couple wanted to do things differently this time around and they found a way to bond over an adrenaline-inducing zip lining trip.

"So for our honeymoon, we were very like, beach bums," Amy said in her confessional. "This time, I was like, 'I want to enjoy Cancun in a different kind of way.'"

Amy and Dillon tied the knot in September 2015, and the famous Duggar family's favorite cousin got her own one-hour Counting On special as cameras followed along on her one-year wedding anniversary vacation.

The Marriage Boot Camp: Reality Stars alums bonded over their mutual love for anything that gives them an adrenaline rush — which is why zip lining across the jungle together seems like the perfect way to bond and celebrate their first year of marriage.

"I love adrenaline," Dillon said. "Anything that's fast, anything that can get the heart going. If I die, I'm gonna do it."

But their wedding anniversary isn't the only big celebration the couple had last September! Amy turned 30 years old on Sept. 30 and her hubby pulled out all the stops for his wife's birthday with a surprise party.

While Amy headed out with a pal for the day, Dillon got to work getting her party set up. He picked up the catering for the event — which included a tray of macaroni and cheese. Instead of a traditional birthday cake, Dillon opted for cupcakes and he even added an extra-special touch by ordering the cupcakes in the same flavor and filing as their wedding cake.

The biggest surprise of all is the new cat that Dillon bought for his wife! He explained Amy really wanted a second cat so he gifted her with an adorable little kitten.
