Fosslaug is a geothermal pool located very close to the Reykjafoss waterfall, where hot spring water flows from cracked rock, an interesting feature in itself. It’s a great spot for relaxation.

Fosslaug is situated on a man-made island between the Huseyjarkvisl River and an artificial canal. From the nearby parking lot (GPS: 65.499083, -19.379456), it’s about a 5-minute walk.
