Frequently asked questions
Do I need to book hot springs in advance?
Spa-style lagoons (Blue Lagoon, Sky Lagoon, Mývatn Nature Baths, Forest Lagoon, Krauma) — yes, especially in summer and on weekends. Free natural hot springs (Reykjadalur, Seljavallalaug, Hellulaug) — no booking, just show up.
How hot is the water?
Most pools are 36–40°C. Some natural streams (like Reykjadalur) vary by location — walk further upstream and it gets hotter, downstream cooler. Always check the ground temperature with your hand before stepping in.
Are hot springs open in winter?
Yes — geothermal water doesn’t freeze, and snow around a steaming pool is part of the magic. Some F-road springs (Landmannalaugar) close in winter; coastal and lowland springs stay open year-round.
Can I bring kids?
Most spa-style pools welcome children, often with a kids’ pool. Wild hot springs vary — slippery rocks and hot water near the source mean younger kids need close supervision.
What’s the etiquette before entering?
Iceland’s rule, hard rule: shower naked with soap before entering any pool. This is non-negotiable in public pools and a sign of respect at every spa-style lagoon. Saves a lot of side-eye from locals.
