A good workout today here at Cathedral Rock Trail. It is about is 3 mile moderately strenuous out and back trail.
To get there take US 95 north from Las Vegas to State Highway 157/Kyle Canyon Rd. Then turn left and follow the road to the Cathedral Rock parking area which is approximately 100 yards prior to the Mt. Charleston Lodge (you'll see the uphill road to the parking area directly ahead of you just prior to the lodge).
The starting elevation will be 7,600 feet and gain about 1,000 feet over the course of the hike. It's an easy-to-follow trail the entire route with no scrambling. The trail starts off steep, flattens out some before you reach the top.
It gets your heart pumping as you ascend. Once at the top, it offers some amazing views of Kyle Canyon and the small community of vacation homes there.
I recommend at least a liter of water per person, some high energy snacks, binoculars, good hiking shoes, and a camera.
