Mt Coonowrin is one of the peaks forming the Glass House Mountains, and part of the Glass House Mountains National Park.
Mt Coonowrin is also known as Crookneck, the meaning derived from the Aboriginal word coonoon-warrang. Aboriginal tales tell that Coonowrin is the son of Tibrogargan (father) and Beerwah (mother), and after running off in a storm instead of looking after his mother, his father hit him on the back of the head and he hasn’t been able to straighten his neck ever since.
Mount Coonowrin can be seen from the Mt Coonowrin Viewing Point, along Murphys Road. There is no specific area marked out, only a brown sign on Old Gympie Road indicating 100m up Murphys Rd.
I found a better spot is a further 300-400 metres further on Murphys Road, where the mountain isn’t obscured with a power pole in the view. There isn’t as much room on the side of the road, but it wasn’t busy with only one other vehicle coming by the time I was there.
Mount Coonowrin can also be seen from a different perspective from the summit of Mt Ngungun 
, lined up in front of Mt Beerwah and worth the walk to the summit.
The entire Mount Coonowrin section of the park is closed from public access and is only accessible with a permit or written approval. At the end of Murphy Road is where the park starts, and a sign is displayed showing it is closed.
Climbing was allowed in the past, but it was a difficult and dangerous climb, only suitable for experienced rock climbers. Serious injuries and deaths have occurred 
on Mount Coonowrin, prompting the park to be closed off. With unstable rocks that may fall, the whole section of the park has been closed.
