Hi Natasha
Thanks for reading my blog.
The climb up that hill would be much easier in a 4WD 🙂
To get to the gorge, have a look at Google Streetview here: https://goo.gl/maps/uFegNVVCc6n
You drive up Waterfall Creek Road, past the camp ground and cross the creek one final time before the steep climb. Just before the start of the hill, on the left, is a dirt track which will lead you to the gorge. It’s a perfect swimming spot.
Enjoy!
Neil

I visit the upper portals all the time. I usually take the 4wd up to cleared ridge car park and hike the route that your rode from there but I’ve been researching alternate routes which is how I came across your blog.

I’ve also summitted Mount May from starting walking from the campsite and what has be currious is your photos. Where is the gorge/ waterfall/ swimming hole accessed from! I had no idea that was there and I’ve passed through the campground 6 time!
