21 Affordable Spa Destinations for Ultimate Relaxation Without the Splurge

13. Secret Lagoon (Gamla Laugin), Iceland: Geothermal Simplicity

Escape the crowds and higher prices of the Blue Lagoon at Iceland's oldest swimming pool, the Secret Lagoon. Located near the Golden Circle, this natural hot spring offers a more rustic and intimate experience. Float in the geothermally heated water (around 38-40°C), watch a small geyser erupt nearby, and enjoy the surrounding steam vents. The entry fee is significantly lower than its famous counterpart, providing quintessential Icelandic hot spring relaxation without the splurge.
