The pass is closed from mid-October through early June. If you plan on riding this during mid-late June, be prepared for some wet roads, and possible light snow near the top of the pass. For information on road conditions, you can call the State Highway Department at 800-226-7623.
Would like to hear from anyone who has ridden Skalkaho Highway between Philipsburg and Hamilton, MT. I am particularly interested in road conditions. Using Google Street View, it's diffiuclt to tell whether the road is paved, and there is a gap in coverage that includes the pass. I am also interested in when the road usually becomes passable. I am hoping to use it as part of a trip that I would like to do in mid to late June.
