We are planning a trip to Glacier Park and the Tetons this summer. I was looking at taking Hwy 287 out of Helena to the West entrance of Yellowstone, then 287/26 to Jackson. Anything I should be awa...
Haven't done 287, but no problem (other than possible traffic) getting through Yellowstone to Jackson. You can also take route 20 down to Idaho Falls and then route 26 to hit Jackson from the south, but it's a lot longer.
Route 22 between Victor and Jackson is not an option due to steep grades/sharp curves.
