String Lake is located off an internal road that runs throughout the Grand Teton National Park.  String Lake a narrow waterway that appeals to recreational kayakers and canoers.  It has a variety of good picnic areas and the trail circles the lake.  It is a nice leisurely hike, depending on how far you want to go.  There is a bridge toward the end on the front side of the lake.  Once on the other side - the loop can be hiked or it branches off for other hiking.  When there is no wind there are some really nice reflection opportunities.
