Hengifoss is a majestic waterfall located in East Iceland, standing at 128 meters tall, making it the third tallest waterfall in the country. The trail leading up to the falls is a popular hiking route, surrounded by basaltic strata and red clay layers. Visitors can also spot fossilized trees along the way. Don't miss the smaller Litlanesfoss waterfall nearby and keep an eye out for the mythical sea wyrm in Lake Lagarfljót. It's definitely worth the 50-minute hike to experience this natural wonder!
