Rumer, Scout and Tallulah all spent the holiday weekend together in Idaho's Sawtooth National Forest and captured the experience with several photos.
The trio took a dip in a nearby river and posed in their swimwear for a group photo.
Rumer, 29, can be seen on the left in the red top and black bottoms. Scout, 26, is on the right with the orange top. Tallulah, 23, is shown in the middle with the red ensemble.
Tallulah posted another photo of herself with the caption, "Dedicated to everyone who called me ugly at 13."
Scout shared a couple more photos of her self during the getaway in her "natural habitat" and "taking a plunge" in the ice cold river.
