It was unseasonably hot when we visited and the ice cold mist of the falls felt so good. There are a couple trails that take you to the falls, we walked the more wooded one in and the beach trail back out. The spring was a little late in 2013, but I found some flowers for photos on the way- I'm sure July is beautiful.
The trail board says 20 minutes each way- I would allow 10-20 extra minutes plus photo stop time. The trail winds around a little, though not much elevation change- it is an easy walk, I guess time just passes quickly. The distance is 0.8mi each way on natural ground.
