Located just north of Jackson, Wyoming, Grand Teton National Park provides stunning views of the Teton Range. I rate Grand Teton National Park a must see either as a stand alone visit or combined with a it's northern neighbor, Yellowstone National Park. My favorite spots for photographing the Grand Teton are Schwarbacher's Landing and Mormon Row.
Schwarbacher's Landing, located between Moose and Moran off US191, provides one of the only drive up access points to the Snake River with direct views of Grand Teton. The first light of day hitting the mountains is well worth the early wake up required to arrive before sunrise.
My other favorite location is Mormon Row, located in the Antelope Flats area. Mormon Row features abandoned homesteads including the T.A. Moulton Barn, perhaps the most photographed barn in the world.
