Red Rock Canyon is a day-use area only, but you can find log cabins nearby at Mount Charleston Lodge. It's only about 15 miles as the crow flies from Red Rock Canyon, though you'll have to skirt back round Vegas and take Highway 157 to get there. The 23 single and double cabins here are fairly upscale, but there's also camping if you want to keep things rustic. You read more here: http://mtcharlestonlodge.com/index.html
