Kristen Bell, Dax Shepard share photos from family vacation with their daughters

Kristen Bell and Dax Shepard are enjoying what's left of summer on a family vacation with their two children.

The "Frozen" actress, 42, shared a slideshow of Instagram photos on Tuesday featuring herself and husband Dax Shepard, as well as their daughters Lincoln, 9, and Delta, 7, enjoying the great outdoors on the Snake River in Swan Valley, Idaho.

In the photos, the family is seen hiking, observing wildlife, horseback riding, swimming and rafting. As usual, both Lincoln and Delta's faces are covered in order to protect their privacy.

Bell thanked Jimmy Kimmel and wife Molly McNearney in the caption of the post for being the "best hosts in the biz." She also shared a photo of a large group enjoying a meal together, tagging pals Jason Bateman and Adam Scott, as well as several others.

Shepard, 47, recently shared a few posts to Instagram from the family's vacation with their RV, which they've nicknamed "Big Brown."

The "Parenthood" alum posted a slideshow of photos from the family's time at the river, including one of him and Bell sharing a romantic kiss and another of the family visiting Mount Rushmore National Memorial in Keystone, South Dakota.

"Humidity. Sunsets. Olfactory bliss. Kind hosts. #BigBrown in a meadow, complete with a 50 amp outlet. Pontoon jungle cruise. Dearest Summer, please never end," he wrote in the caption of the Aug. 16 post.

"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 a separate post dated Aug. 13.
