I parked my car at the bottom of Platte Clove Mountain Rd along the 6 foot fence. The early part of the unmarked trail is very easy and one can reach 4 or 5 waterfalls within an easy 30 minute walk. The waterfalls range in size from 3 feet to nearly 20 feet. After this relatively flat section the mountainous ravine of Platte Clove closes in and it becomes very difficult at parts to hike and to continue. The boulders are tremendous and there are many.The last photo in the series is of a waterfall about 50 feet in height- maybe taller. It took me nearly 1.5 hours to get to this point- which is only 1.5 miles. (I did take several  breaks to take photos.)
I used my GPS receiver to get waypoints and distance to the Devils Kitchen parking area which is located on the upper portion of Platte Clove Road. According to my GPS receiver I made it to within .2 miles of where the parking area is located. The parking area is another probably well over 200 feet up and at many sections Platte Clove becomes nearly vertical. There is a waterfall that can be seen from the top of Devils Kitchen that may measure taller than Plattekill Falls (over 70 feet). This waterfall is named Bridal Veil Falls.
The hike was amazing and it is somewhat like hiking in Utah. My trip took place before all the heavy rain of 2005 in the Fall season so the creek was a bit sluggish.
