For a close encounter with Luxembourg's industrial past, make time for a visit to this blast furnace once used for steel production. Furnace A can be explored both independently or as part of a guided tour; those who make it all the way to the top will be rewarded with sweeping views of the surrounding areas.

If you like adventurer and always striving to experience something new and wild, then paragliding might be your thing.

Founded in the 7th century by St Willibrord, the patron saint of Luxembourg, the Abbey of Echternach contains a fascinating scriptorium — once the most important in Medieval Europe — in its cellar, with manuscripts dating as far back as the 11th century. Part of the abbey complex, the Basilica of Saint Willibrord contains a crypt with the saint's holy remains. A dancing procession that draws visitors from all over the world (Saint Willibrord Pageant) is held in the town annually on Whit Tuesday.

The Blue Lagoon is without a doubt the most well-known geothermal spa in Iceland. The signature milky-blue water makes a stark contrast to the surrounding black lava fields and creeping grey moss. The spa is located in a lava field near Grindavík and is supplied by water used in the nearby Svartsengi geothermal power plant. The water temperature stays at 39°C year-round, snowfall or sunshine. Most visitors make the spa their first or last stop, since it's conveniently located only 15 minutes from the Keflavík International Airport (and around 30 minutes from the capital city). If you are buying a tour, it makes most sense to combine the spa visit with the Golden Circle day trip.
