Although a very nice walk, this hike to Sawyer Burn Hut was most memorable for the chance encounter with a completely nude hiker. (Well, he was wearing hiking boots). Alas, it was a somewhat portly middle aged man, but he did make quite an impression. Presuming you won’t meet any such person, you can instead expect to remember nice beech forest, great views of lake Hawea, and views of high peaks towards the end of the track. You can apparently walk past Sawyer Burn Hut and climb Sentinel Peak for even more views, but we didn’t have enough time or energy on the day we did it.
We used track notes in Day Walks of New Zealand: Central Otago and Queenstown, and there is information on the DOC website. It’s a pretty straightforward walk of moderate difficulty.
