Stunning views!! I had the summit fully to myself and seldom encountered other hikers which was both amazing (it's a beautiful day! The world should be hiking!) and glorious. A few backpackers and day hikers, but overall pretty quiet. And the summit-- wow! The west overlook has great rocks to enjoy the view, but I preferred the east overlook and it's 360 panorama.
A few logistics for those who may encounter the same questions I had:
-- several cars are parked at the trailhead for the AT; keep going to the parking lot, which has both ends of the trail's loop.
-- the trail is now called the Henry Lanum Memorial trail; the Mt Pleasant trail is solely for the .5mi trail to the summit, which juts off the main loop.
-- the full loop is 7.3mi (including the one mile steep up and back for the summit trail)
Solid loop with good views. If you park in the first lot you come to on the gravel road, you will hike the trail counter-clockwise, which means that you will get the great views from the summit meadows sooner rather than later (which is how my group hiked it).
I'd recommend continuing to the second, larger parking area and hiking clockwise so that the best part is closer to the end of your hike. Views from the clearings at the summit are really awesome and are very unique among Appalachian hikes I've been on as there is practically 360 degree visibility.
I.m. P. on Mount Pleasant Trail
The last half mile or so of the road to the parking area isn't paved. Lots of loose gravel and bigger rocks in the road. NB.
Trail starts off pretty flat but evevuanlly there's a steady incline. Moderate and not too difficult.
Once at the top you can view either East or West summits. Clouds were rolling in on the day I hiked so there wasn't much of a view....but seeing the clouds actually roll in was pretty cool.
Great views from Mt. Pleasant! Did this hike with my two daughters, 12 & 10, they both loved it. The top is somewhat strenuous. The Henry Lanum trail could be better marked, especially when leaving the fire service road. You pass by some great Rhododendron that fill the path. Total time out and back with nice 45 minutes at summit for us was 5 hours. We did not go over Pompey. Here is the view from the top: http://goo.gl/7TN7W
