Whiteoak Canyon is one of the best waterfall hikes in Shenandoah Valley National Park. There are six waterfalls ranging from 35 to 86 feet and many smaller cascades along the Whiteoak Canyon Trail, making this trail one of the most popular places to hike in Shenandoah. During the warmer months, the swimming holes along the way are great places to cool off, but expect lots of company. Being one of the most popular hikes in the park, it can be very busy in the peak seasons of spring and fall.
