The classic Bonnington Traverse from Bombi Summit in the south to Barrett Creek to the northeast.
The route is described in sections between each of the huts:

Day 1 - Bombi Summit to Grassy Hut

From Bombi Summit, either (a)follow the powerline road/right of way north for about 6.7 km (some annoying ups and downs) and then turn to the east (near tower #154) and skin up to reach the pass between Grassy and South Grassy; or (b) follow the Munson Road system (go R at 3.7 km and 3.9 km and L at 5.4 km - all kms marked) for 6.4 km to the second of two small spur roads that exit to the east. The correct spur road begins to go uphill immediately and is about 100 metres after the first. Follow this spur road up for a couple of switchbacks, then where the road levels out, leave the road and climb to the broad pass between Grassy and South Grassy. Descend 80 (vertical) metres to the east to theGrassy Mountain Hut.

Day 2 - Grassy Hut to Steed Hut

From Grassy Hut ski back up to the pass and continue skiing north to the top of the west ridge of Grassy Mt. Ski east along this ridge until you can descend down the north ridge of Grassy Mt to a broad pass at GR643625. A major road (Munson) runs through this pass. Continue skiing north over to the top of two minor unnamed peaks (known locally as Twin Peaks).

From the most northerly of the Twin Peaks, either (a) stay on the ridge and ski down to the pass at the height of land between Glade and Granite Creek; or (b) follow the north ridge of North Twin Peak down until it is possible to drop off to the east and ski down to a logging road that leads into the height of land between Glade and Granite Creeks. Both routes meet at this point.

From the height of land between Glade and Granite Creeks, ski up to the pass on the south ridge of Siwash Mountain at GR673658. One way to do...
