In October 2025, after a day of rain, the trail (not a path) through the gorge was muddy and slippery, and at one point, the stream had spread across the path. It's manageable with waterproof shoes with tread. The path must have been easier to navigate in the past. There are remnants of steps and many felled trees that have been roughly cleared out of the way. Despite the criticism, it's still an experience.
