The Frozen actress, 42, shared a carousel of snapshots to Instagram on Tuesday — featuring a rare glimpse at the couple's daughters, Lincoln, 9, and Delta, 7, whose faces were covered with heart emojis — from their recent trip with friends and family to Swan Valley, Idaho.
"Thank you @mmcnearney and @jimmykimmel - you're the best hosts in the biz," Bell captioned the post, tagging late-night host Jimmy Kimmel and his wife, Molly McNearney.
The carousel of pictures showed the family of four exploring the Snake River, horseback riding and enjoying the views. One photo featured what appeared to be a big dinner party attended by Kimmel, McNearney, Jake Tapper and many others.
Shepard, 47, also posted a handful of photos from his summer adventures, captioning the post, "Humidity. Sunsets. Olfactory bliss. Kind hosts. #BigBrown in a meadow, complete with a 50 amp outlet. Pontoon jungle cruise. Dearest Summer, please never end. #deadpresidents."
In the first photo, he can be seen dipping his wife and giving her a kiss while the sun appeared to set on the water behind them.

Over the weekend, the Armchair Expert podcast host also shared Instagram photos similar to those posted by his wife. "Heaven isn't a place on Earth, but rather many many places on Earth best seen from behind the wheel of #BigBrown," he wrote in the caption.
Last month, the actress told PEOPLE that the family was ready for their two-week "annual summer motorhome trip."
She added at the time, "We're going to go to Idaho and visit some friends, and our girls love camping and love being in the motorhome. Shockingly, our family does really well in close quarters so I'm hoping that that will be a good summer ender before we go back to school."
Bell also explained that, while the family was ready for some summer fun, her girls were also looking forward to getting back to school after their vacation.
"My kids, they love being at home during the summer," she said, "but I think they are getting antsy to be back in a situation where their brains are challenged and their bodies are challenged at recess and they can talk to their friends."
The actress — who recently teamed up with SpinMaster and Paw Patrol — also shared her advice for parents raising young kids.
She told PEOPLE, "Do not be afraid to use your support system has been a really valuable piece of advice for me. It's one thing to know you have friends and family, a neighbor, a cousin, whatever, but it's quite another to pick up the phone when you need something."
