Commercial lagoons

Blue Lagoon (Reykjanes) — the famous one. Booked weeks ahead in summer.
Sky Lagoon (Reykjavík) — newer, infinity edge, “ritual” steam circuit.
Hvammsvík (Hvalfjörður) — quieter, ocean-side.
Mývatn Nature Baths (North) — like a smaller Blue Lagoon, far cheaper.
GeoSea (Húsavík) — sea-water geothermal, fjord view.

Town pools (sundlaug)

Every Icelandic town has one. Entry ~1 200 ISK. Real swimming pool + several hot pots at different temperatures + a steam room. The Reykjavík pools (Laugardalslaug, Vesturbæjarlaug, Sundhöllin) are excellent.

Free / natural

Reykjadalur — a hike-in geothermal river south of Reykjavík.
Hrunalaug — very small, fragile, please respect.
Landbrotalaug — fits 1–2 people, again fragile.

Etiquette

Shower naked before entering. This is non-negotiable in Iceland.
Lower your voice in the hot pots — locals chat quietly.
Don’t enter natural hot pots in shoes or with dogs.

Frequently asked questions

Is the Blue Lagoon worth the price?

For a one-time spa-style experience, yes. For an authentic local soak, no. Sky Lagoon's "ritual" is more memorable for similar money.

Are there free hot springs in Iceland?

Yes — Reykjadalur (hike-in river), Hrunalaug (very small, fragile), Landbrotalaug. Treat them gently; they get destroyed by overuse.

Should you do the local town pool instead?

At least once, yes. Sundlaug culture is genuinely Icelandic and 10× cheaper than the lagoons.

Do you need to shower before going in?

Yes, naked, before entering the pool. This isn't optional and isn't a tourist thing — locals do the same. Signs explain the rules in English.
