Paulina Hot Springs are man-made hot springs located along the lakeside of Paulina Lake in central Oregon.
Starting at Little Crater Campground, head north toward the hot springs (43.730, -121.247). If you're really looking to stretch your legs, you can extend the out-and-back hike to a full loop around the lake just shy of 8 miles. The water in the springs is around 95 degrees, and doesn't smell of sulfur. You can even dig your own spring on the North Beach.
