Spruce Knob is West Virginia's highest peak and on a clear day offers breathtaking 360 degree views from the Observation Tower. https://www.fs.usda.gov/recarea/mnf/recarea/?recid=7053
Because of the thick conifer growth, long mountain views don't occur till nearly to the top and that only along the western roadway...but once you climb the observation tower...(as mentioned, on a clear day) you are rewarded with wonderful views of WV and VA mountains. Watching storm clouds or simple clouds roll in and envelope the Knob offers a wonderful experience.
I've taken the opportunity to camp on Spruce Knob on several occasions, once to the NE of the parking lot just into the pines, once a couple hundred yards down the Seneca Backcountry trail to the right and once directly south of the Tower in the pines. Each offered a differ experience. There is no cost, which is a huge plus!
In the pines, just below the summit, it is eerily quiet and muffled. I've never seen another camper when I've stayed, so the solitude is glorious.
If you want shelter and a picnic table for cooking/eating...they are available, but only along the parking lot. Pit latrines are nearly on the summit in the parking lot near the trailhead for the Observation Tower. So practice leave no trace when camping and hiking!! No water, so bring enough with you. There are waste receptacles but be wise and take trash with you.
There are two levels to the concrete Observation Tower...and best views are from the upper level. I've often though about cowboy camping on the second level after the last sightseer has left for the night, but haven't seen, heard or read if its forbidden or permitted...so I haven't...yet.
Obviously, on a clear night, star gazing is incredible as there no ambient light. It is much cooler at this elevation, even in the summer...and the winds on the summit cut through like a knife.
Note: utilize good camping practices and set camp on a previous location where there is an established fire ring. Again, use caution with campfires because of the wind.
If you desire a more established campground, Spruce Knob Lake Campground is not too far away...down the mountain.
Spruce Knob summit camping is a family highlight!
