The boardwalk loop (30\u201345 minutes) crosses the field at safe height with the steam columns close enough to fog your glasses and the sulfur aroma doing its honest work. On cold days the steam builds cloud-plumes visible across the peninsula; on calm days the mud pools perform for whoever stands still.<\/p>\n<p>The setting is raw: no spa infrastructure, no visitor centre beyond the signs and the paths \u2014 the field is what the Blue Lagoon (#nearby) sits on top of, in its unbuilt form.

The Reverend Eir\u00edkur of Sta\u00f0ur was called to deal with her; the legend says he lured her to the spring and trapped her inside it with his Bible, where she remains \u2014 the steam, locals will say, is Gunna still boiling.<\/p>\n<p>The story is told on the field\u2019s interpretive signs and repeated in every Reykjanes retelling \u2014 it is the peninsula\u2019s folk identity marker, and it explains why a boiling 20-metre spring carries a first name.
