Grjótagjá is a small lava cave located near Mývatn in northern Iceland, known for its picturesque geothermal hot spring. The cave's interior is illuminated by the crystal-clear, warm waters that fill the pool, creating a striking contrast with the rough, black lava rock surroundings. Historically, Grjótagjá was a popular bathing spot, although bathing is now discouraged due to fluctuating water temperatures caused by volcanic activity.
