Probably the most unique hike I’ve done! I’d call it a moderate hike, first part is easy it’s like walking on sand (annoying but easy) then hiking up the cone is the killer part. It’s only a half mile up, but your legs are going to burn. The painted dunes are what I was looking forward to the most, and they exceeded my expectation. Very unique and beautiful! Also I’d recommend hiking down in the the back trail of the cone, you get great views of MT Lassen, Brokeoff, and you get to walk in the lava flow and dunes a bit.
