It's a fun hike. Powerline pass always has gorgeous scenery. The hike is pretty easy, mostly level until the very end. Not one of my favorites in the Anchorage bowl, but it's a good short hike. Usually takes me about 3 hours to complete the whole thing from the parking lot to the lake and back. The terrain is just a rocky/dirt path, fairly easy to navigate.
Okay so the way me and my friend got up was a much more intense and much quicker way up but the view from the top is incredible. It doesn't matter how you get there just as long as you get to the top to see the amazing view of Anchorage and the mountains across the water. I highly recommend taking this hike
