No one told me this was Australia’s scariest tourist attraction! Climbing a 75 m fire lookout tree seemed like a good idea at the time… age 66 and in my prime. Karri trees can grow up to 90 m (295 ft) and are among the tallest trees in the world and the highest trees tourists can climb anywhere. In Western Australia, there are two giant fire lookout trees that visitors can climb, both located near Pemberton in the old-growth Karri forest. Join me as I clamber up the tallest lookout tree in the world, the 75 m high Dave Evans Bicentennial Tree in Warren National Park. The viewing platform on the Bicentennial tree, at 60m, is about the same height as the top of the Sydney Opera House. How can you climb a 75 m high tree without using ropes or wearing a harness? By using spikes! No, not on your feet…in the tree. 165 giant spikes have been driven into each tree at regular intervals to form a spiral ladder. Wire-netting has been added all the way up to enclose the spiral, and I can tell you from personal experience that it is a welcome safety feature. Climbing spikes spiral 200 feet or 60m up the Bicentennial tree. Photo by G. Sranko As a visitor from Canada it struck me that there is no way you would be allowed to climb a tree like this in North America, given liability issues and the degree of risk. Apparently only 20% of climbers make it to the top. No one has died, but a couple of people have had heart attacks after the climb. My wife Jan was wise. She stayed at the bottom close to where I would land. Base of the Bicentennial tree. Photo by G. Sranko There were originally eight karri trees used as fire lookouts between 1937 and 1952. In the case of the Bicentennial tree I climbed, 165 spikes were driven into the tree in 1988 as part of Australia’s bicentennial celebrations. The 62 m Gloucester Tree, in Gloucester National Park, was turned into a lookout tree in 1947, with 153 spikes. Yes, the Duke of Gloucester was visiting Pemberton as the lookout was being built. Too bad it wasn’t Big Bird! (Big Bird Tree would have a nice ring to it.) Both lookout trees offer spectacular views of the old-growth Karri forest. The Climb After the first 100 spikes I noticed my thighs were getting a bit sore. Looking at my face in the photo below you might discern a touch of nervousness. Not fear, mind you, just concern associated with my body telling me that I was doing something dangerous and stupid. What the hell am I doing up here? Photo by G. Sranko The spikes appear to be big and sturdy until you step on them. Then you realize that they are only about an inch in diameter and hard on the feet, especially for tourists wearing flip-flops. I was wearing sturdy hiking boots and the spikes still made an impression on my sole. When you arrive at the first platform about half-way up, there’s a sign reminding you "THAT WAS THE EASY BIT!" The toughest part is still ahead. The spiral gets even steeper and narrower. Fortunately, I was alone on the spikes, I can’t imagine trying to squeeze past another person, especially at the narrow bits near the top. A good reminder: "That was the easy bit!" Photo by G. Sranko As I climbed higher and higher, my wife on the ground below became tinier and tinier. It started to really sink in that I was climbing as high as a 20-story building on skinny metal spikes. One of the most disconcerting aspects was the view down between my feet. The spike I was standing on seemed very insignificant and surrounded by a lot of nothing. Spikes and thin air. Red arrow shows Jan reading at bottom. Photo by G. Sranko It struck me that one slip would be either very painful or potentially deadly. Slipping off a spike would mean landing hard in a straddled position and crushing my balls. This was the best-case scenario! If I didn’t straddle the spike, it would be a lot worse to ricochet off the spikes and wire-cage below, tearing my fingers on bark and metal trying to break my fall. I could envision broken bones, a cracked noggin, or no noggin at all! That’s the worst part. Your mind starts to invent all sorts of scary scenarios. Better to stay focused, one spike at a time and not spend much time looking straight down. By the time I had climbed 150 spikes I was getting tired. My thighs were aching because whoever drove the spikes into the tree spaced them for an 8-foot spider not a 6-foot geezer. Each step up was a big step and then came the next, and the next, and the next… Platform number 2. Now we're getting somewhere! Photo by G. Sranko The view from the top platform was fantastic. I felt elated at my accomplishment and gazed all around to soak in the view of the old-growth Karri forest spread out below me. The beauty of the Bicentennial tree is that it is so tall that you stand above the rest of the forest canopy and witness the splendour of a sea of treetops below. Watch me climb 200 feet in 3 minutes! The Descent As I looked down the long, long spiral straight below I realized I was only half-way there. Back to work, one step at a time! Thigh master here we come! A quick rest on the way down. Photo by J. Cadieux You get into a rhythm, but there’s no way to avoid looking down. If you don’t place the ball of your foot exactly right on the next skinny spike below…well, you know. You need to watch exactly where you step. The platform half-way down provides a good resting spot for weary thighs and sore soles. As I neared the bottom, a couple of young ladies stood waiting for their turn. Luckily for me they waited since there’s not much room for passing on the spikes. I thought they looked rather sparsely dressed for the occasion, and both wore the inevitable flip-flops. They started climbing with trepidation and kept glancing down. After about 20 spikes they called a hasty meeting of the minds and made a good decision. That was far enough! I was glad to see them head back to earth. Soon a group of three Aussie blokes arrived. They were enjoying a beautiful sunny day out with the lads and had fun taking photos around the spikes at the base of the tree. Flip-flops, of course. Don't wear these if you want to make it to the top. Photo by G. de Germain on Unsplash I’ll admit that Aussies have tough feet from spending so much time barefoot, but I don’t think it would be possible to climb to the top wearing flip-flops. The spikes are just too skinny, and a person’s entire body weight is focused on that one narrow pressure point with each step. I think that helps to explain the 20% that reach the top. They’re probably wearing boots or shoes. These three blokes were laughing and joking, pushing and shoving, for the first 30 spikes. Then they slowed down as the fun began to wear thin. Like one-inch diameter thin! They had another good laugh and decided to head back down. Seems like there’s a high-attrition rate for climbing the famed fire lookout trees of WA. Shame, really, so many people are missing out on reaching the top of Australia’s scariest tourist attraction! Overlooking the canopy of old-growth Karri trees. Photo by G. Sranko Old-growth Karri forests The biologically unique forests of Western Australia are separated from the forests of eastern Australia by several thousand miles of desert and scrub. They provide essential habitat for a wide range of endemic plants and wildlife species found nowhere else. Surrounded by giant trees in the Karri forest. Photo by J. Cadieux Karri (Eucalyptus diversicolor) is the tallest of the eucalypt species that grow only in Australia’s south-west corner and nowhere else in the world. The other giant eucalypts growing in this region are the jarrah, marri, and red tingle. Karri can live 300-400 years or more and reach full height after only 75 years. The fire lookout trees are likely over 250 years old. Bicentennial tree is one among other giant Karri trees. Photo by G. Sranko Karri has a long, straight trunk with smooth bark that it sheds each year. The outer bark changes color with age, with beautiful patchworks of pink, orange, grey and white. The trees produce white flowers in the spring, but only once every seven to 10 years. The nectar is highly sought after by birds, possums, and insects. The local Karri honey is considered heavenly in flavor. Australian ringneck parrot in Karri tree... beauty of an endemic. Photo by G. Sranko Karri is a prized hardwood species that has been logged extensively in past centuries. Before the arrival of Europeans, these forests covered about 3,600,000 hectares in the southwest of WA. Karri forests now cover less than 200,000 ha (490,000 acres). How do you get to the fire lookout trees? Go to Pemberton, Western Australia, and head to the visitor center. The Pemberton Visitor Centre has information and maps for the climbing trees. They will even sell you a climbing certificate. Don’t forget your National Park Pass, required to enter the national parks where the trees are located. The centre is open 7 days a week from 9am to 5pm. National Park camp sites There are excellent camp sites in Warren National Park. We stayed at Draftys Camp right beside the Warren River. Draftys has two camping loops with 22 shady camp sites, toilets and a camp kitchen with picnic tables and free gas barbecues.
