The drive to the trailhead was absolutely gorgeous - tons of fall colors, fog, and a few lakes. The dirt road was filled with many potholes and about 3 deep puddles that filled the entire road and one place where you have to drive through a flowing creek.
Trailhead was easy to find - it's labeled Cathedral Pass - got to the trailhead at about 10am and there were only 4 other cars in the parking lot. The beginning of the hike is all in forest with no views but there were endless varieties of mushrooms and some fall colors which made it interesting. Someone had posted a warning note that there was an active yellow jacket nest at the base of a boulder; thankfully I didn't see any yellow jackets when I passed by. Squaw lake was very beautiful- some fall colors around the sides, ducks swimming across it. Heard a woodpecker and some frogs croaking. After squaw lake you pass by a few more small scenic ponds.
As you near the top of the hike the views become absolutely breathtaking - great views of mountain ranges, cathedral rock, and looking down at deep lake. There was mist/fog/low clouds that morning that had mostly burned off by the time I got to the top. Saw a very long waterfall originating from snow melt then coursing down the side of the mountain all the way to deep lake. The turn-off for the PCT north trail is on the right and I missed it on the way up because the sign on the tree is angled but I saw it as I came back down - it's before you get to the view of deep lake.
There were some nice rocks to eat lunch on with an amazing 360 degree view.
The trail to Peggys Pond looked pretty sketchy so I turned back there; so did another set of hikers.
Only came across 3 other sets of hikers the entire time - this is a nice hike for those who enjoy solitude :)
