Often September brings beautiful, warm sunny days and cool nights. The camp cook will prepare hearty western meals in dutch ovens over an open fire. You'll never leave the campfire hungry. Weather in the Tetons is unpredictable. Summer days average in the 70's and 80's with the evening temperature dropping into the 40's and 50's.
Thunderstorms are a common occurrence.
From my experience, the Tetons are beautiful in all kinds of weather. We provide most everything. You just need to bring your sleeping bag, fishing gear, and personal gear. I suggest a sleeping bag with a temperature rating of 20 degrees. Please pack your personal gear in a water-proof duffle and limit the weight to 35 pounds.
