It is not a secret anymore, yet it is pretty touristic. Since Blue Lagoon gets fully booked pretty often, Secret Lagoon is the alternative that locals usually recommend to visitors. Surrounded by hot springs it is highly scenic indeed, but do not compare to the Blue Lagoon; it is completely different. Not fancy at all but all natural. Unlike Blue Lagoon, Secret Lagoon does not limit the number of visitors so it can get pretty crowded in summer.
Erupting in every 6–10 minutes and surrounded by a highly active geothermal area, Strokkur geyser is an absolutely must-see location. It is located on the Golden Circle, within 1,5 hour driving distance from Reykjavik. It is lesser known that there is another geyser on the Golden Circle, the "Little Geyser", just next to the Secret Lagoon in the village of Fluðir
Beautiful geothermal lagoon with unique milky-blue colored water. Even celebrities are fan of this place. The water is technically waste water from the geothermal power plant, but absolutely safe to swim in. It is naturally warm and rich in silica and other minerals but the Lagoon itself is man-made.

The majestic Jökulsarlón Glacier Lagoon with the Diamond Beach is located in southeast Iceland, close to the ring road. It is one of Iceland's most spectacular natural wonders.

Do not skip visiting this natural wonderland when you travel to Iceland!
Kirkjufell is the most photographed mountain in Iceland. No wonder why! It is located on the Snaefellsness peninsula, a few hours drive from Reykjavík. Visiting this beautiful nature park is an ultimate day-trip that I highly recommend!
