If you get to Grand Teton, you might also take a boat cruise on Jackson Lake. They have regular cruises that go out and around Elk Island, over to Moran Bay in the shadow of Mt. Moran and than back to the marina. They also have lunch and dinner cruises that go to Elk island for lunch or dinner on the shore looking over the lake to Mt. Moran. Jenny Lake is beautiful, but you can get a bit closer to the base of Mt. Moran on Jackson Lake. We generally, in the three trips there each year, fish at least part of the time, in Moran Bay. One of the prettiest spots we have been to in our lives. Although we haven't been everywhere.
