Everything is explained very well here, and an overview map makes it easier to get your bearings. It's amazing how much vegetation exists less than 5 meters from a boiling hot pool.

Only those who make the effort to climb the steep climb will be able to enjoy these views. But at the top, you'll know why you did it.

Anyone visiting Seltún will be amazed at how closely the area resembles a lunar landscape. With its red, somewhat unreal gravel and steaming vents, the area is dotted with bubbling mud pools, fumaroles, and hot springs.

The half-hour of elite fun costs a mere 44,000 ISK (around 300€) per person. Furthermore, this tour is not for people who have difficulty walking as you first have to hike 3 km over hill and dale to the crater.
