The Canyon Baths is located near Husafell in West Iceland. It features two natural hot pools heated by volcanic activity under the earth. From the pools, you can also cold plunge into the stream. Also known as Giljaböð it opened in 2019 so not a lot of people have been to this gorgeous location! I highly recommend adding this hidden gem to your itinerary!
*Please note that this hot spring is on private property and can ONLY be accessed via booking a tour.
