@Serenity_Luna On the right-coast, Dolly Sods and/or Grayson Highlands area, 3rd place, Roan Highlands area, NC. Currently in 4th place, Seneca Creek, WV due to numerous waterfalls.  The common theme here is 'not in a tree tunnel'.

In the middle, anywhere in the Bridger Wilderness, Wy; Maroon Bells 4 pass loop in Co, or Weminuche wilderness, CO.

On the Left Coast, it would have be the JMT, 2nd place, anywhere in the Sierra.

Canyon and arch hikes in Utah, or 'slick rock' hikes like the Boulder Mail Trail in the Grand Staircase Escalante, are absolutely fabulous!

Oh gee, can't forget the Grand Canyon, hmm, that area ties as my first place favorite.

So many places, running out of time.
