The Bonnington Traverse

Hut to Hut skiing in the Kootenay Powder Belt

alpine ridges linking steep tree skiing

The Rockies are known for the great glaciated hut-to-hut traverses: the Wapta Traverse and the Yoho Traverse (or the “Bow-Yoho” Traverse as it’s also known). Deep in the Kootenays is a completely different kind of trip, the Bonnington Traverse. This is a 3-day (with heli-drop) or 4-day traverse that links alpine and sub-alpine ridges from Ymir all the way to Porto Rico, just a few minutes drive south of Nelson.

a great mid-winter ski adventure

Due to its lower elevation, this trip is a good choice in a wider range of mid-winter weather. The exception being when pineapples roll in (warm wet storms) or late in the season — early April is about as late as you ever want to try the Bonnington. It’s non-glaciated — meaning lighter packs! — but has a lot of great treeline and bowl style skiing.

The huts are small, quaint and cozy, fitting a half dozen ski tourers comfortably. I really enjoyed doing this trip in April 2016. The skiing is excellent, and it really is a Kootenay classic for the bucket list.

Day 1 – From Castlegar we will enjoy a short helicopter flight to Grassy Ridge. From here there are a number of excellent ski descents to hit on way to Steed Hut, our first night’s stop – a nice, deluxe hut in a great location.

Day 2 – From Steed Hut we make our way along the east side of Siwash Mountain and upper reaches of Eerie Creek towards Copper Mountain Hut. Almost the opposite of our previous night’s abode, Copper is an old log relic built in the early 1980s with a lot of rustic class!

Day 3 – The highlight of the Bonnington is the traverse of the ridge between Copper and Empire.  The views are stunning, and the skiing opportunities are absolutely fantastic. The day finishes with a long — but downhill — tour along Barret Creek the road and our shuttle back to Nelson.


The 4-day trip is exactly the same as the 3-day trip except that we start at the road near Bombi Summit and ski in to the Grassy Hut. The ski is very pleasant and takes us through rolling cutlines and cutblocks up to the ridge connecting with Grassy Mountain and then gently down to the obscure site of the hut.


It’s easy to turn this trip into a 5-day trip by adding an extra night at the Steed Hut or by adding the Huckleberry Hut on to the end of the trip. Contact us for details on pricing for this option

We will meet in Nelson, BC the night before the trip starts. On the morning of the first day we either proceed to the heli pad (for heli-accessed variations) or drive to the trailhead. A shuttle driver will bring your vehicles back to Nelson to a safe location for parking during our trip. They will then pick us up at the trailhead at the end of our trip.

Beginner to Intermediate Ski Tourer, “Relaxed Pace” overall; overnight packs (up to 30 lbs/14 kg)

A gear list for the week is attached below. Despite being a mid winter trip you should bring ski crampons. They can make a big difference even on a powder skiing week at times. If you have any difficulty obtaining these please let me know. I have some spares and can likely set you up with a pair. A lightweight ice axe may be useful for some of the lines in the area, especially late season (late March-April-May) but if you don’t have one or aren’t interested in that kind of skiing then don’t worry about bringing one.
