There are tons of picnic tables at Sealy Tarns, and the recommendation would be to take a good rest here and eat before you embark on the third and final part of your excursion. The trek to Mueller Hut – which is a technical and challenging climb.
At least that's what I did. I took a straight hour to rest, had a quick nap on the bench, recharged, refuelled and did absolutely nothing.
On the way to Mueller Hut
This part of the trek is hard—no sugar coating. The recommendation would be to have hiking poles with you because it will make life easier. However, if you don't, you can still survive, but basically, you will be scrambling over boulders and slippery rocks for a fair bit of the journey.
What is non-negotiable are functional, sturdy rock climbing boots.
There are two demanding sectors to navigate. A set of boulders and a stretch of slippery rocks before you can make it to the flat ridge which looks up to Mount Sefton. From there the landscape changes and becomes flat, but there are still some more boulders to scramble over before you can get a clear shot at getting to Mueller Hut.
The stretch of small slippery rocks before the ridge is the most difficult part and honestly speaking there is no shame if you have to crawl on all fours to keep your balance and a secure foothold. It won't be anything remotely close to cool alpine climbing, mostly, more of scrambling, but with a little bit of effort, patience and time it is doable.
