Our verdict
Seljalandsfoss is the unmissable stop on any Iceland south coast road trip — and one of the most photogenic and experiential waterfalls in the country. Count 1 hour on site for the main waterfall + Gljúfrabúi nearby (often forgotten by tourists). Our tip: arrive before 9am to avoid crowds, bring a waterproof and waterproof shoes, don't forget a waterproof bag for camera gear, and absolutely explore Gljúfrabúi 600 m to the north (enter the fissure on foot in the river — wet feet guaranteed). In winter, the walk-behind trail is closed for safety reasons, but the waterfall itself remains accessible from the viewpoint and offers an exceptional frost spectacle.
