You meet at Reykjavík’s City Hall before dawn, the air carrying a thin salt tang from Faxaflói Bay. A private van idles, steaming in the cold, while the guide checks the day’s window of weather on a tablet. Then the road opens: sweeping lava fields punctuated by moss, low mountains skirting the horizon, and the kind of sky that can change from sun to sleet in half an hour. This two-day loop stitches together Iceland’s headline landscapes — tectonic rifts, geysers, plunging waterfalls and a black-sand coast — with the tempo of a private tour, stopping when the light and appetite demand it.
