The Gallatin Avalanche Center gives updates daily. The National Forest has a rental cabin at the trailhead as well as a campground. The Cabin is great for a multi-day accents. We opted to camp in the Saddle above. This is bear country and during our descent we came across the largest Grizzle paw prints I'd ever seen so be aware of your surroundings in spring and summer.
Drive to Cameron, Montana on State Highway 287 take the Bear Creek Loop road east after several turns of a right then left then right again then take a left onto Bear Creek Road East to the trailhead. From there you take NF Trail 325 along Trail Fork Bear Creek until the trail climbs up out of the forest into open alpine.
Depending on your snow avalanche conditions, you can take the trail to the saddle between The Helmet and The Sphinx or the saddle between Black Mountain and The Helmet. Due to the snow pack talking to us with whoops of collapsable snow and moderate avalanche ratings at the time we skied, we opted to ski from the saddle between Black and Helmet mountains staying as much as we could to slopes under 30 degrees.
