Skinny Dip Falls: This three-tiered waterfall along the Yellowstone Prong drops a total of 30 feet through a rocky bend in an ice-cold mountain stream. Perched on the edge of the tallest falls is a rock that juts over a deep plunge pool. While we can’t say that the waterfalls are amazing compared to some of the larger cascades found just a short drive away, we do think this adventure is worth the effort due to the deep water hole and proximity to the Parkway. We recommend working up a good sweat by exploring the nearby Mountains to Sea trail.
