Read more about this trail

The Karri boya-k (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 Karri boya-k (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. 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 Porongurup Ranges were devastated by fire in 2007 and in the years since the flora of the region has shown its resilience in its fight to return to its former glory. It is a well-known fact that in the years following a fire, wildflowers and orchids in particular flower profusely.  The Eucalyptus trees re-shoot and the moss and grasses start to grow again.  

This part of the Porongurup Ranges is a beautiful spot to simply sit back and enjoy nature and watch as this place continues to flourish post-fire. From the Karri boya-k (Tree in the Rock) picnic area there are several walk trails to choose from, short 30 minute walks to more experienced bushwalks which take over five hours.

The Porongurup Range, located in WA's Great Southern region, is an internationally recognised biodiversity hotspot. The ancient granite range supports over 1200 native plant species, including 10 endemic species. The diverse vegetation types provides habitat for a wide range of native animals, including several endangered and vulnerable species. 

The unique climate and elevations create a damp, protected environment that sustains a rich mix of towering forests and colorful shrublands. The upper slopes feature magnificent stands of towering Karri forest, an outlier from the main deep-south karri belt. The lower slopes are cloaked in open Jarrah, Marri and Yate woodlands. Spring (August to November) brings the forest floor and shrublands to life with over 55 species of orchids (including the Purple Enamel and Cowslip orchids), mountain bells, flame peas, and banksias. Over 300 macro-fungi species have been identified, making it an incredible destination for fungi enthusiasts.

Porongurup National Park is home to a rich array of wildlife, and visitors can frequently spot Western Grey Kangaroos, Brush Wallabies, and Brushtail Possums. The range is also home to nocturnal marsupials like honey possums, pygmy possums, and quendas. Over 100 bird species have been recorded here. Look out for the Rufous Treecreeper, Scarlet Robins, and Western Yellow Robins. The old-growth trees provide crucial nesting hollows for threatened black cockatoos, including the Carnaby's, Baudin's, and Forest Red-tailed Black Cockatoo. The damp forest floor and moist gullies harbor various skinks, goannas, carpet pythons, and ground frogs.
