I have been a frequent visitor to John Forrest National Park since I was a child but I had never explored the area surrounding the Glen Brook Dam. The Glen Brook Trail starts and finishes at the main picnic area opposite the Jane Brook Bridge and is marked with a blue triangle. Leaving from the north-west corner you cross over Glen Brook via a stone footbridge and head along side the brook. Being summer, there was no water in the brook, in fact I don’t think there would have been much water in there at all this year as even Jane Brook was dry for most parts. We hadn’t been hiking for too long before we came across an old 1930’s picnic shelter. These shelters are nestled throughout John Forrest National Park, this one was overlooking another picnic area on the other side of the brook, accessed by a small bridge. We continued on the narrow windy paths rising slowly up towards the dam, nothing too strenuous, just a beautiful hike through the woodland of marri, jarrah, wandoo and the Balga trees were in abundance. I still can’t believe I had never visited this area before, such a lovely trail to walk along, so vibrant and tranquil.

We then reached the Glen Brook Dam wall and were welcomed with crystal clear water, apparently no good for swimming though due to bacteria. The Glen Brook Dam was built in the 1960’s to provide additional water supplies for the park, I believe it still serves the parks water requirements but has also been used to fight local fires. Following along the western side of the dam we came across a beautiful granite outcrop set right back amongst the trees.  We spent some time here admiring the beauty wondering how many thousands of years old the outcrop must be. Continuing on to the southern end of the dam we crossed over Glen Brook via a small bridge, although Sophie had fun jumping across the stepping posts that would have been previously used. We stumbled across a couple of small kangaroos, heard plenty of much larger ones but we were clearly too noisy as we only ever heard them jumping away. The trail then rises again over a small ridge as we make our way back to the dam wall. Offering elevated views of the dam, this little section was really quite special to walk through. Once again Balga Trees lined the path as it meandered closely to the dams edges. We paused here for awhile perched by the dam edge on some rocks, immersing ourselves in our surroundings, in awe of the serenity of the area.

We reached the dam wall, which could also be a starting point for anyone wanting an even smaller walk, and Sophie tested her rock climbing skills on another beautiful granite outcrop before we then descended down back onto the trail again through burnt jarrah forrest, a result of some recent burn offs. I actually really love walking through areas like this. The variety of colours in the regrowth is always quite spectacular. Made our way over a few more small bridges and we were back at the start. It took us 1 and half hours but we really immerse ourselves in nature so our time is always longer then most.

We hope this blog inspires you all to start planning your adventures throughout Australia's biggest state, best known for its spectacular landscapes, breathtaking beaches, wildflowers, wildlife, rugged coastlines and ancient regions.
