Cheers Josh, yep, Coronets up there with my hardest day walks for sure, scrub tends to sap the energy pretty quickly.
I have been to Mt. Wright with the intention of the Stepped Hills, but unfortunately almost killed a non-walking mate just getting to there so just explored that range (awesome arch feature at the Nothern end a must see - natural engineering wonder!). Good work on that one, I might go via Lake Gordon next time.
Probably my other three hardest day walks were Clear Hill & The Thumbs in a day (probably similar to Stepped Hills terrain wise) - about 9.5 hours, Jubilee Range in 6 hours at pace & definitely Mt. Bobs in a day at 11.5 hours (my favoutite day walk ever!). Not sure if that ones been tackled as a day walk before.
Do love the big day missions; Saturdays always best tho as you're not gonna move far on the Sunday
Stu.
