WaypointsTree-in-the-rock picnic areaThe 'Tree in the Rock' picnic area, set among the karri trees, almost has the feel of a cathedral, with the towering karris providing the domed roof. The tree in the rock after which the site has been named is just 100 metres along a shaded walk. Extending its roots down through a crevice, this mature karri clings to existence on a granite boulder. Many unusual rock formations make the Porongurup Range a fascinating place for picnicking and bush rambles. The Tree in the Rock picnic area is a haven for birds, such as the rufous treecreeper, golden whistler and brilliant scarlet and yellow robins. Footpaths lead to several peaks, other paths cross the range, and a nature trail leads through the forest near the Tree in the Rock.-34.67578, 117.87117 Bolganup Heritage TrailEasy 600m, 30 minute circuit. Walk through karri forest along a path that crosses a small creek. The karri (Eucalyptus diversicolor) trees that grow on the slopes of the Porongurup Range are a remnant from former times. Karri forest grows exclusively on a deep red soil known as karri loam, and needs at least 700 millimetres of rain a year. Fossil pollen found in many places throughout WA indicates that in an earlier, wetter era karri forest grew far beyond its present extent. As the climate became drier, the forest gradually retreated west to its current stronghold between Manjimup and Walpole. In places where the soil was suitable, and the rainfall remained high enough, small outlying populations survived. Hence, a virtual island of karri forest still survives in the range. Porongurup National Park is in the process of recovery from a severe wildfire that swept through the park in February 2007. The fire started outside the park and quickly spread through grassland into jarrah, marri and karri forests, burning nearly 90 per cent of the park's 2,500 hectares. On the northern side, the fire swept up the peaks so fiercely that it defoliated most of the forest canopy. On the slightly moister southern side, the fire was milder. The habitats of most Porongurup flora and fauna species were damaged by the 2007 fire, some severely. As these habitats recover, many species will recolonise the range. Many species of wildflowers, especially orchids, flower profusely during the early years following a fire. However, forests take many decades to recover.-34.67585, 117.86974 Wansbrough WalkWansbrough Walk is 4km one way. It is a delightful walk through karri forest along a gully between Nancy Peak and Devils Slide. Wansbrough Walk intersects with the Nancy Peak Trail and Devils Slide Trail. It then continues to the park's southern boundary and becomes a road that connects with Millinup Road. Some visitors leave a second vehicle at the southern end of the pathway and start at Tree in a Rock. If you have arrived at the Wansbrough Walk via the Nancy Peak Loop, it is 1.6km back to the picnic area, mostly downhill. Colonial botanist James Drummond, who visited the range in 1843 and 1848 to collect plant specimens for shipment to other botanists in England, described the karris as 'the finest trees I have ever seen in any country'. The majestic karri is the tallest tree in Western Australia, sometimes reaching 80m high. The trees growing at the Porongurup Range, however, only attain heights of about 40m. They are able to survive in the range in sheltered gullies and in places where there is more moisture from run-off.-34.67815, 117.85424 Morgan's ViewMorgan's View is considerably lower than Hayward or Nancy Peaks. You can see the aptly named Devil's Slide, a large steeply sloping area of bare and moss-covered granite, to the west. After taking in the views, you will have to clamber down a rocky path that is quite steep, and rocky and loose underfoot, so take great care.-34.68086, 117.85695 Nancy PeakIt is possible to take a strenuous 5.5km, 2-3 hour circuit from the Tree in the Rock picnic area. The trail heads up the northern side of the range and then along its very spine, up and over Hayward Peak, Nancy Peak and Morgan's View then back along the Wansbrough Walk. Carry plenty of drinking water. There are stunning views from Nancy Peak southward to Albany.-34.68199, 117.86227 Hayward PeakYou can undertake a medium 3km, 2 hour return walk from the Tree in the Rock picnic area to Hayward Peak and back. Make sure you carry plenty of drinking water. About 100m from the start is the Tree in the Rock, a karri that found a foothold in a crevice and gradually enlarged it as it grew. Karri and marri are the most dominant trees in this area, while karri hazel, karri wattle and tassel bush form part of the understorey. Australian bluebell can be recognised by its small bell-like mauve flowers from October to February. The track climbs sharply upwards. Passing a small track that veers to the left, you should continue along the main path. Hayward Peak is situated 1.73km along the walk from the picnic area and provides great views to Stirling Range National Park. You can also see a dam below. Look for a plaque that gives further information about the peak.-34.68086, 117.86811 Reviews (0)Photos (0)Recordings (1)No one has reviewed this trail yet. Be the first!
