Hi, I've been up/down the Gully Route a few times in winter and summer. From the carpark it is 99% walking or very low angle scrambling, though all in a very alpine environment. The crux is the gully right at the top, which is only 40m or so high and tops out metres from the summit. The gully is an easy rock scramble when dry (or easy snow climb in winter), though be warned there could be snow in the gully even end of summer but usually so little that it can be easily managed without snow gear. Hard to put a grade on it (10?), and there may be some loose rock here and there but there is plenty of solid rock on the walls for gear and to bridge over loose stuff. There are two rap stations so you can get down with a single 60m rope (if I remember correctly).
