Fodor's Expert Review Kerlingarfjöll Mountain Resort

Over the years, this remote mountain complex has featured a campsite and A-frame huts alongside a low-key restaurant in a beautiful setting, but now it's enjoying a complete overhaul under the guiding hand of Blue Lagoon, getting new life as an upscale hotel with lodges, a glamping area, a campsite, and lagoons tapping into the local geothermal waters. It's in an area with several shapely peaks, steaming valleys, and canyons riddled with hiking trails. It's 10 km (6 miles) off Route 35, along Route F347.
