More ways to explore the area's outdoor wonders
You step off the van and the valley inhales: steam threads between grass and lava rock, a low river hisses like something alive. A guide points the trail up a gentle rib of heath, and within minutes the city’s hum is gone—replaced by the soft crunch of pumice underfoot and the distant metallic scent of sulfur. This is Reykjadalur, the Steam Valley, and its geothermally warmed river invites hikers to earn a soak.
