Orange Is the New Black [1] actresses Taylor Schilling, Uzo Aduba, Yael Stone, and Adrienne C. Moore traded in their prison uniforms for bathing suits during a vacation in Hawaii in late December, and it looked like they had an absolute blast! The group put their Christmas caroling [2] on hold so they could brave the pouring rain to go for a muddy hike together, goof off in the ocean, and laugh their way up and down the big island. Since the release date of OITNB's fourth season [3] still hasn't been announced, any glimpse of Litchfield's most hilarious inmates is a good one. Keep scrolling to see more photos, then check out the best quotes from their hit show [4]!
