The swimming pool/hot spring Seljavallalaug is situated in a short and a narrow valley near the farm Seljavellir at the foot of the Eyjafjöll Mountains in South Iceland. The local Youth Club built the old and unique pool, where a still older and smaller one stood before. One of its long sides is the sheer mountainside, where natural hot water trickles into it. It has a splendid view of the nearby stream cascading down from the mountains and must be one of the most beautiful settings for a naturally heated pool – anywhere. The "natural" pool is somewhat of a well-kept secret by locals and is very well frequented by local youths – especially during midnight sun of the incredible everlasting summer evenings.
