This trail to the Swan View Train Tunnel is popular for birding, hiking, and mountain bike riding.
Located within the Shire of Mundaring this was a great bushwalk around the very popular Lake Leschenaultia.
A very easy walk, perfect for young kids to check out native Australian plants before a swim in the lake.
Also saw a pair of very cute fairy wrens.
Mount Bruce is the second-tallest peak in Western Australia at 1235m and lies about 36km west of the park office. The walking tracks on the mountain provide a great opportunity to view the Marandoo Mine Site located to the south. The easiest walk is the Marandoo View which is a 500m walk and takes about 30 minutes round trip. For a slightly harder walk, you can take the Honey Hakea Track which is a 4.6km round trip that is about a 3 hour journey.
Highest mountain of WA at 1249 m.
You can actually drive to the top but would require a 4WD.
A nice steep walk to the summit of Mt Nameless (known to the local Aboriginals as Jarndunmunha). The summit is a great place to check out the sunset and view the surrounding mines. Mountain is located right next to the town of Tom Price.
The third highest peak in Western Australia and the highest in the Stirling Ranges located 4.5hrs South East of Perth. The range is very prominent rising high above the predominately flat terrain. The walk itself is very well marked and attracts a lot of tourists of varying ages and fitness levels. Most people of reasonable fitness can climb it in under 2hrs with lots of time to rest and enjoy the view. At the top you are greeted with a panoramic view of the National Park, Stirling Ranges and beyond.
