Beautiful! Overlooks the lake. First hill is tough!

Challenging hike with a lot of steep climbing. It's pretty exposed, so start early and bring a lot of water if it's going to be a hot day. I was carrying a heavy pack for training and I ended up going through 5Ls of water.

There's a big blowdown blocking the entire trail near the trailhead. Bushwack a little to the left to get around the tree - I'm sure a trail will get carved out by folks soon enough.

There's no waterfall right now, just a small bit of water wetting the rocks. Actually, it looks like there's a nice scramble / climbing line up the rock when the waterfall is dry - might bring better shoes to give it a try next time.
