Wear hiking shoes or a footwear with good grip as the wooden/rocky walking paths are a little wet in some stretches.
Bring your rain ponchos or waterproof jacket because a lot of water is dripping from the walls and ceiling and there is no shelter if it start raining.
Inside the gorge is much cooler than it is outside, so bring a light jacket.
The gorge is wheel chair /child stroller accessible form the west entrance. Walk up-to the east end where stairs starts and return back to west entrance. Walkways are secured with metal guard rails.
