Seltún has one of the most striking and surreal landscapes in Iceland - dramatic red, green, and yellow colored hills frame an expanse of steaming volcanic vents and boiling hot springs.

A well-maintained boardwalk winds through the bubbling and hissing field and information signage explains the geology of the geothermal area. Strong hikers can climb to the massive steaming vent (solfatara) at the top of the hill for a spectacular view of the ocean, the fields and the lakes.

Many study opportunities due to the great variety of features. Seltún has many mud pots and fumaroles, and minerals deposited from geothermal solutions provide colorful sediments. Good walking paths are around the area and parking.

Seltún is a part of Reykjanes nature reserve.

Location: Road 42, parking, near Kleifarvatn.
