I personally consider all the trails in Yosemite to be spectacular.
You have to take the good with the bad.
I can take you on a Mono Meadow trip into Illouette Hole that will knock
your socks off scenery wise.
Anyway, to me Yosemite beauty and uniqueness is all due to 2 things.
Waterfalls and Granite Domes. Since it is not early in the year the
loop I suggested was all for seeing the "best" (IMO) of Yose.
Lyell is awesome as is Evelyn, Vogelsang, Hanging Basket... but to me..
those aren't so unique ... there are literally hundreds of those places in the Sierras. and even Lyell is somewhat boring until you get 8 miles down
canyon.
(that being said the wife and I are going thru Vog area next week...)
(Guess I have a passion for the place and love it all)
Anyway, enjoy
