Beginning at Jenny Lake in Grand Teton National Park, this ride follows the park road to Spalding Bay. The traffic can be heavy on busy park days, but the scenery is always spectacular with the Tetons majestic spires to the west. Spalding Bay is on the southern end of the large Jackson Lake. Jenny and Jackson Lakes are deep lakes created by glaciers. Jackson was made larger by a dam. The ride between the two lakes is relatively flat.
