June 2016... LOTS OF SNOW! Trail can be difficult to find thru snow but just follow to crest & you are rewarded with a beautiful clearing & spectacular view of Broken Top, South Sister !!!
Lake was frozen over! Absolutely breathtaking!

Lots of little waterfalls to see at the beginning. Dogs love it if they are fit.

I have been to Green Lakes so many times I decided to make the left hand turn to Moraine Lake and am glad I did. The trail is easy and you are rewarded with the lake. I had some food from my backpack there sitting on a log next to the water. After lunch I headed up the south sister trail.

OK, admittably by Oregon standards I am a lightweight. Getting there was OK, exhausting... But OK. Amazing view. So much snow at this time of the year. Getting down however was miserable for me, slippery and very steep in spots. We backpacked, great spot once you get there.

This was a tough one for me coming back down. Lots of tree roots, steep terrain and really tired legs! Views are wonderful. Take snacks and sun screen.

I was exploring all day and came across this trail head and decided why not? It was a warm day at the base of the mountain, but as you ascend into the trees and along the beautiful creek, it gets chilly and there was snow almost up to my knee. I was one of only five people out there, and after getting to top and looking down on Moraine Lake was so beautiful. I stayed and ate and then noticed a dog coming to me, I decided it was time to go down at this point but since there was so much snow I could barely find my way back. The dog helped me half way down mountain running with me, till a whistle came and dog ran away. Awesome beautiful hike.

It's a hard, high altitude hike that takes you into one of the most beautiful areas in the cascade mountains, if you continue straight you will summit south sister, continue east and you will end up at moraine lake and eventually the green lakes, head west and you will go to wickiup plains. The pumice plain is a pristine alpine area with great views of broken top, Mt. Bachelor and south sister. On a clear day you can see the rim of Crater Lake. Not for inexperienced or unfit hikers.
