From the Routeburn Shelter, start running back down the access road, past the Routeburn Station Homestead as far as Scott Creek. Follow the Scott Creek route all the way to Scott Basin, taking care not to go left at the first creek (topo map and compass recommended!). Once in the Basin, head left along the creek. At the watershed between Scott basin and Kay Creek, it's possible to either head into Death Valley over the col, or directly to Kay Creek Hut. The direct route is given on the GPX file, but it's the least preferable, as the descent is extremely steep, slippery and full of bluffs. Once at Kay Creek Hut, follow the orange markers down the valley to join up with the Caples Track. Turn right and head over McKellar saddle into the Greenstone. On joining the Greenstone, turn right towards Howden Hut. Complete the Loop via the Routeburn Track.

Features of interest
Plenty of Beech and Alpine flora and fauna, though you won't have much time to take it in if you want to finish in daylight!

Start is at the Routeburn Shelter Car Park.
Large safe parking area.
The route up Scott Creek is often overgrown. To pick up the orange markers from the first stile, head for the large clump of steep bracken that's closest to the creek. Reasonable map reading skills are required to make it through to Death Valley. If you are unsure, don't try this route (the clue is in the name!). The track from Kay Creek Hut is well marked with orange triangles and follows the true right of the river.
