Wadsworth (Big) Falls is a very popular park for most of the populace in Middletown and surronding towns and will generally have a heavy number of visitors during the summer months. Here, again, Adobe Photoshop will be your friend when editing your images and removing stubborn visitors from the pictures.
Wadsworth (Little) Falls, however, is the much lesser known little brother to the big falls and thus will generally have much fewer people to contend with when shooting both falls so I would plan accordingly.
Both falls, however, will provide quite a nice series of shots if shot when the light is right and/or the leaves have turned in the Fall.
