Trip Info

The world’s oldest National Park sits atop a super-volcano and features Earth’s largest collection of geothermal features. The Tetons contain some of the oldest rock in North America – 2.7 billion-year-old metamorphic gneiss. Experience the superlative beauty of Yellowstone and Grand Teton National Parks, with the added expertise of our backpacking guides.


Yellowstone and Grand Tetons have very extreme weather – in fact, the highest recorded difference in temperature in a 24-hour period was recorded in Montana at over 100 degrees! July can be warm and dry in the day, but cold in the evenings with highs in the 70s and lows in the 30s. It can snow any month of the year and often does!
