Went here at the peak of fire season this last Summer. Stayed at Paulina Lake campground ($25/night cash only) to get a bit of elevation and out of the reach of the smoke. Campground was very nice and found a spot right on the lake. Took a scenic walk to the north side of the lake where some dig-your-own hot springs can be found and a few pits that occur naturally. To see a bit more of local geomorphology check out the Obsidian flow nearby and don’t forget about Paulina Falls on your way out
