The Jenny Lake area looks best
when it's at it's greenest and the wildflowers are in bloom.
For most years this takes place from mid to late June. Hidden
Falls on the far side of the lake is a popular photo spot.
It is best shot on an overcast day when the highlights in
the cascades won't become 'blown out'.
In my opinion the hike there and the wildflower show you see on the west side of the lake beats the falls as a photo attraction. In late June the white columbines and lady slipper orchids can be quite photogenic.
