Every now and then, the Blue Mountains puts on a show that feels completely unreal. Phantom Falls is one of those.
It's not actually a waterfall. There's no water. What you're watching is cloud, moving so slowly and so deliberately over the cliffs that your brain keeps trying to tell you it's liquid.
What's actually happening
Warm air rises from the Jamison Valley and meets cooler air drifting across from the Megalong Valley side. When the humidity is high and the morning is still, usually after a night of rain, fog starts forming along the ridge. As the sun comes up and warms the eastern slopes, parts of the fog begin to clear, but the cooler air keeps flowing over from the Megalong side. The result is this slow, misty cascade that spills over the cliffs and dissolves into the valley below.
The best conditions are early morning after rain, clear skies, calm winds, and enough of a temperature contrast between the two valleys to keep it moving. Autumn and winter give you the strongest contrast, so that's when it tends to happen most. But you can't really plan for it. You just have to be there on the right morning.
Where to see it
Phantom Falls forms along Narrow Neck Plateau, the long sandstone ridge that separates the Jamison and Megalong Valleys near Katoomba. The cloud spills off the cliffs when the fog and air currents meet at just the right angle. Get there early, before the sun burns through, and find a spot with a clear sightline across to the ridge.
What it felt like
I'd seen photos before, but photos don't quite do it. The clouds were moving like liquid, folding over the edge of the cliffs and dissolving into nothing. Everything was still. The light was changing every few seconds. I remember just standing there not really wanting to move.
Capturing it felt surreal. One of those mornings where you're glad you got up early.
