I got the idea for this traverse here . I downloaded the linked GPX file to my Suunto Ambit 3 and it worked great.
If you are comfortable with over 2000m of ascent and the same in descent, exposed scrambling, and you love being completely committed on a long mountain ridge traverse, this is for you!
The scrambling is never overly difficult, though there are a few spots - particularly on the descent of Porcupine ridge - where a fall would be a disaster. The route finding is generally quite easy - follow the ridge line and faint path, though there is a little bit of bushwalking on the climb to the first summit from Baldy Pass and on the descent off Porcupine, where I lost the main trail a few times.
Be prepared for a lot of hands-on-knees style hiking - it's a grunt in places!
My time was 4h 21m car to car, with a few photo stops and I didn't do the short optional side trip to Belmore-Brown Peak. If I'm up there again I would definitely add this one in.
Have fun, and let me know if you've done it.
