Blue Lagoon (Bláa Lónið) – famous geothermal spa near Grindavík (serves many Keflavík visitors)
Best time to visit
Early mornings offer soft light and noticeably fewer people. Evenings are atmospheric as steam and lights rise, and winter visits increase chances of seeing the Northern Lights.
Budget tips
Standard admission usually starts around €60-€100 depending on season and time, premium packages cost more and add towels, masks and drinks. Bring your own towel to avoid rental fees and book online several days ahead for lower-priced slots; check combo tickets that include airport transfers for modest savings.

About
Snabba fakta: Milky-blue geothermal water averages around 37–39°C, feeling silkier than most hot springs because of its high silica and mineral content. Pools and wooden walkways sit among black lava fields, and the facility circulates millions of liters of mineral-rich water daily from nearby geothermal runoff.
Höjdpunkter: At twilight, plumes of steam hover over the electric-blue surface and the contrast with dark lava creates an almost otherworldly glow that photographers chase for golden-hour shots. Visitors have a ritual of smearing chalky white silica mud on their faces for 10–20 minutes, the gritty paste drying to a matte mask before being rinsed away to reveal noticeably smoother skin.
Insider tips
- Book the first or last entry slot of the day to avoid peak crowds and enjoy quieter pools.
- Leave metal jewelry in your locker before entering, silica and minerals can cause discoloration.
- Carry a plastic bag for wet swimwear and a small headband to keep hair free of silica mud.
- Use the boardwalk near the changing rooms for classic photo angles of blue water against black lava and the ocean in the background.
