The map makes it look really easy - just a contourless plateau, then a nice ridge line, a hump, a saddle and then up. Fun. The Abels book mentions a little scrub en passant, but makes no big deal about it. The reality was a lovely plateau walk along the top of Walled Mountain, a ridge line with mighty drops between many boulders so that the less agile members of our party needed time and care and help to negotiate the challenges, then a plunge to the saddle that some found rather nervy. And then the hard bit began - the bashing through VERY thick scrub. The final climb up an almost sheer pile of boulders was a breeze, and the most enjoyable part of all, even though it looked rather daunting from a distance.
