We are not sure that should we finish visit Yellowstone National Park first, than go to Grand Teton, or exit Yellowstone National Park at the south entrance than visit Grand Teton Nationa Park?? Because from the map the Grand Teton is close to the south entrance of Yellowstone National Park??
Also we plan to camp througout the trip, is it possible? if it is possible, shoud we stay in the same or different camp site in the Yellowstone National park??
Thank you so much.
