Victor – Jackson – Teton NP – Flagg Ranch – Yellowstone NP – West Yellowstone
If you don’t mind pavement and some tourist traffic you can make a grand bike loop all the way around the Tetons and up through Yellowstone NP back to West Yellowstone.
From Victor there is a bike path east to Moose Creek then you’re on the highway to the top of Teton Pass. Here you can either take the main highway down to Wilson or the old highway, which is preferable. It is on the right side just a few hundred feet as you head down the hill into Jackson Hole.
From Wilson there is a bike route to the Snake River, then you can either go north on a bike path to Teton Village and the Moose / Wilson Road to the town of Moose or take the highway into the town of Jackson proper. From Jackson there is a new beautiful separated bike path through the south end of Grand Teton NP to Jenny Lake. After that you’re on the roads with tourist and RV traffic north to Flagg Ranch. At Flagg Ranch you can either go west on the dirt Grass Lake Rd. (see description) or continue north through Yellowstone NP to Old Faithful and West Yellowstone. This route is the Adventure Cycling’s “TransAmerica Trail” used by the pavement tourers to cross the country.
