Soon enough I am back at the junction where I spotted the Splendid Fairywren. That's pretty much it, I continue along the track back to the large concrete tank and finish the West Terrace Walk. It's 9:45 am, so the official West Terrace Walk took me about 1.5 hours to complete. I need to get home though, and because it is a Saturday the public transport options are limited. My best option is to walk along Kalamunda Road to Hawtin Road and take the 296 bus at 10:21 am back to the city.
In conclusion, the West Terrace Walk is a rather short walk, with some steep rocky sections which kept my heart rate up and my lungs out of breath. It's an ok walk, but there is much better in Mundy Regional Park (the Palm Terrace Walk and Lesmurdie Falls and Whistlepipe Gully and Lewis Road Walks). I think the southern and mid sections of the park are much more interesting. For example, there is significantly more wildflower action in the south. The ecology of the park appears different at either end of the park.
Anyway, I now feel like I have conquered Mundy Regional Park after exploring the north. Goodbye and happy trails!
