A good cut marked track runs along terraces on the north side of Lake Sumner. 1.5km after the Marion turnoff a short track is signposted on the south side of the main track to an 'observation point' where partial views of Lake Sumner are present through increasingly tall bush.
The crossing of Three Mile Stream was unbridged in 2007, but new topomaps (2015) show a bridge present, so it may since have been rebuilt - check with DOC. This is a large stream in a confined bed and could easily flood after rain, though easily crossable in normal flows. The turnoff to Three Mile Stream hut, up Three Mile stream is signposted on the western bank.
