The Ammo up to Lakes of the Clouds to the summit and then down the Jewell Trail is a good easy trail - but it is long. Pick a good weather day for sure and start early. A day that has iffy weather later can get you caught in a rain storm as you are coming down. (Been there - done that). It is a great hike though.
That was the route I took my son in law on for his first hike on MW - and also when I took my oldest grandson last summer. It was that day we got caught in the rain on the way down.
Here are pictures of the hike with my oldest grandson last summer.
