We’ve just visited Injidup Natural Spa, which is a naturally occurring spa pool of foaming and bubbling water set in a chasm in a rocky headland, in south-west Western Australia. As Indian Ocean waves pour water into the pool it foams and bubbles, creating a spa effect.
It’s winter now, so there was no one in the spa pool, but I can imagine how inviting this bubbling pool would be on a hot summer’s day!
The spa pool is in a chasm in the rock, which runs parallel to the coastline. Another chasm, which runs perpendicular to the coastline, links the spa pool to the Indian Ocean. This chasm tapers in the direction of the pool.
When waves hit the ocean end they are concentrated and focussed as they move along the narrowing chasm until they explosively surge over a rock ledge into the spa pool. When the water plunges down into the spa pool it's been tossed and boiled amongst the rocks and is full of air bubbles, creating the natural spa.
Here’s a wave coming through the chasm, about to enter the spa pool:
This Google Earth view of Injidup natural spa shows the narrowing chasm between the ocean and the pool; the small green pool to the right of the chasm is the spa pool:
Google took this picture on a calm day, so there’s not much water or foam in the spa pool, but when I was there, there was plenty of water pumping through.
Here’s a short video of waves surging through the tapering chasm into the spa pool:
Over millions of years the pounding waves of the ocean have weathered the granite rock of the headland around the natural spa into strange, complex, and interesting shapes; here’s a few examples:
The coastline around the south-west parts of Western Australia that I’ve visited during my current house-sit is all spectacularly beautiful, and the coastline around Injidup Natural Spa lives up to that experience:
This is yet another beautiful spot in Western Australia!
