Just back from the gravel is a marker to the start of the track up the Beans Burn. Under beech, the track rises to a fixed bridge spanning the burn, crossing to the TR. A steep climb to a saddle and a short descent reaches a grassy flat with good campsites. The track resumes at the northern end and climbs away from the burn to 800m and roughly follows this contour back to the stream. There are several major slips and side streams to cross.
Eventually, the track breaks out from the trees and the rock biv can be seen more that a km at the other side of the clearing.

Cross the Rock Burn below the hut and continue along he edge of the Dart River as far as possible (very dependant on flow level).
Scramble up onto the forested bank and pick up a footpad and head upstream, staying close to the river. Drop back to the river when possible and look for a marked entry to a track that cuts through the bush to the Beans Burn confluence with the Dart River. Cross the Beans Burn where shallowest.
Travel time is highly dependant on flow level in the Dart River.

200m upstream of the rock biv, cross to the TL and head towards the obvious saddle, picking up a useful footpad. From the saddle, follow a rocky gut almost to the river and pick up a dry (in normal flow) anabranch and follow to just short of the climb point. Pull out of the shallow rocky bed and cross to the TR and the climb point.
Altitude: 979m to 1544m. Gain: 726m. Loss: 244m . Gradient: 21 deg (Moderate-hard)

Initially in a small gut, the climb to Fohn Pass is fairly simple - go up. As altitude is gained, the pass comes into view - just head for it.
From the pass, climb to the right. Follow a square gut down until the lake come into view then traverse, losing altitude, to the lake. Distributed camping in sheltered tussock is readily available.

Cross the lake outlet and circle the knoll to follow the outlet stream down a spur turning right with the stream and descend easily to the Olivine Ledge (1 hr).
On the broad shelf, head towards the knoll at 1200m (with tarn - camp possible) taking great care as many deep channels and holes could easily break a leg of the unwary. From here the terrain becomes more rocky and Fiery Col comes into view.
Cross the TL arm of Fiery Ck and pick up the footpad that climbs to the Col. Descend into the bowl below the col and stay on the TL of the obvious gut. The route down is cairned and stays close to the gut edge.
At the valley floor, cross a stream and stay close to the slope until through Cow Saddle (as the saddle is quite boggy). Once in Hidden Falls valley, travel is (mostly) fastest on the boulders/rocks in the dry river bed (the water is underground) until around the 780m contour.
Pull out of the creek bed on the TR, to avoid forest on the TL, and descend to the treeline at 720m and cross to a track on the TL. Follow the well defined track through a clearing (good campsite) and continue on the TL until a major side stream is crossed. Now look for where the track turns away from Hidden Falls Creek and immediately begins the very steep climb to Park Pass.

I want to delete this route but apparently Trip 454 is using it????

Pick up the footpad west of the tarn and climb the spur to the large cairn, 1.2km from the pass. Leave the spur, descend and negotiate a small shallow depression (outlined on the map by the 1220m & 1240m contours). The route is infrequently marked with cairns but it is a steeply rising sidle across tussock and scree - dangerous in adverse conditions. Aim to approach the marked stream above the 1400m contour and continue to climb (on the TL) to 1500m. You can travel above the tarn or around to it's outlet - both routes rejoin in the lower saddle (1600m). Continue through the saddle and down to the small tarn (close to the left rock wall is easiest) and proceed to the Lake.
Altitude: 1474m to 1616m. Gain: 171m. Loss: 58m . Gradient: 6 deg (Moderate)
From the north shore of Lake Nerine, walk to the west side and climb to the low saddle. From here there are two routes to North Col.
This route stays high. From the saddle above Lake Nerine, negotiate the large boulders and climb a little to 1560m. Now it's route-finding at it's best - lots of rocks and ridges provide a few challenging moments but the plan should be to stay at 1560 - 1580m, climbing and descending as required.
If visibility is questionable, use the low route.
Altitude: 1405m to 1587m. Gain: 254m. Loss: 141m . Gradient: 9 deg (Moderate-hard)
From the north shore of Lake Nerine, walk to the west side and climb to the low saddle. From here, there are two routes to North Col.
The low route descends to the 1440m ledge and contours around to the gully below North Col - then up. There are useful cairns along the route.
If visibility is questionable, use the low route. The high route takes slightly longer (and would be very challenging in poor weather).
Altitude: 1468m to 1720m. Gain: 339m. Loss: 339m . Gradient: 8 deg (Moderate)

Make your way up the ridge ling near Point 1580. From here the ridge can be climbed north and by picking your way up ledges around small bluffs, Peak 1740 can be gained. The view over Lake Nerine from up here is worth the effort. The rocky ridge can be followed north to Peak 1744 without difficulty. A ridge drops east from Peak 1740 which can be followed down to a low pass west of Point 1594 (the low pass is the route north out of the Lake Nerine basin). Point 1594 has great views down the Rock Burn. The outlet of Lake Nerine is reached via rolling, smooth rock ledges around Point 1508. The outlet stream initially drops gently for a couple of hundred metres down into the Rock Burn valley and has interesting polished rock formations.

In Feb 2013, snow and ice was easily avoided. However, even in summer, the south side of North Col can be fully covered in snow / ice. Without appropriate gear, attempting the descent in such conditions would be stupid.
In good conditions, it's a long descent on boulders, scree and snowgrass. The line is occasionally cairned and obvious. From 1200m contour, aim for the gully to the right of the flattening spur. At 1020m contour, cross to the TL of the burn and pick your way down until a slip suggests easier travel on the TR (870m elevation).
From here the going is easy through grass flats - the start of the marked track clearly marked. Continuing through grassy flats, then around a significant tarn and into the bush, the track rises a little then descends to the final flats leading to the Routeburn Flats Hut. There is no bridge crossing the Left Branch but low flow presents no problem.

Head down Theatre Flat and follow markers into the bush on the true left of the Rock Burn. A short distance later cross the swing bridge over the river and follow a good quality track all the way down river through bush and flats with good camping. The track climbs up the hill past Point 844 and a sign posted track junction reached which points the way to Sugarloaf Pass. Climb and cross the muddy pass and follow markers down into the bush on the Routeburn side. The track drops steeply all the way down to a signposted junction with the Routeburn Great Walk. Follow the Routeburn to the shelter at the car park.

Head south from the rock biv and cross the outlet stream from the Park Pass Glacier melt lake (a difficult crossing on slippery rocks in rapid current). Follow the Rock Burn down stream. A marked track drops down through the bush by the upper gorge and then its down more river flats to climb through the bush beside Point 908 on another marked track. Drop down to Theatre Flat and cross to the patch of bush half way down. On the north side of the bush is a giant boulder with a permanent fire pit on its eastern side and sheltered camp spots.
