Willow Canyon Trail is a 5 mile out and back trail located near Death Valley, CA and is rated as moderate. The trail is primarily used for hiking and is accessible from November until April.
This is a beautiful hike. The beginning of the trail is not well marked, however, its not hard to miss it. From the parking lot, just go left and follow the rocks to the open area. Just follow the washed out area all the way back till you hit the canyon. The trail ends at a beautiful water fall. I hiked this on Thanksgiving '13, and the water was flowing. Its wonderful and secluded and a great spot to have lunch. I highly suggest packing a lunch and enjoying the falls.
The largest national park outside Alaska, Death Valley National Park provides a wide variety of hikes, wildflowers, and waterfalls (yes, you read it right...all are based on the time of year of your visit).
Willow Canyon trailhead did not appear on several DV maps but a call to the Ranger's Station provided the general area which was not too hard to find beyond the lowest point in the U.S., Badwater.
Due to the 50+ foot waterfall at the turnaround point, Big Horn Sheep frequent the area to refresh themselves. The five mile RT hike offers geological wonders plus the chance of seeing the Big Horns.
