The Blue Lagoon in Iceland closes periodically, most recently in early 2025, due to volcanic eruptions, increased seismic activity, and safety concerns related to the Reykjanes Peninsula's, particularly near Grindavík, where fissure openings and lava flows pose risks. The closures are precautionary to protect employees and guests.
Summer opening hours: June 20-August 20, 07:00–00:00 Winter opening hours: August 21-January 31, 08:00–22:00 February 1-June 19, 08:00–20:00 We kindly request that guests exit the water 30 minutes before closure.
The Blue Lagoon has been mostly open during 2024 and 2025, and their team is highly trained in evacuation plans and safety strategies, making sure that if another eruption happens, everyone will be secure.

Is Blue Lagoon waste water?
The Blue Lagoon began as a pool of wastewater from the Svartsengi geothermal plant in 1976. Few Icelanders, if any, had any desire to bathe in it, as the idea of bathing in wastewater from any kind of power plant was considered crazy.
♨ The Blue Lagoon is made of geothermal seawater, and its high concentration of silica is part of what makes it magical for your skin. BUT it makes your hair feel like absolute straw if you dunk your head in the water. 🧴 To prevent this, the Blue Lagoon provides tons of conditioner in the locker room.
What happens when you dip your hair in the Blue Lagoon?
Depending on your hair type and how sensitive you are, you might want to use a shower cap or keep your head and hair out of the water. The Silica in the water is not harmful to your hair, but it can get stiff and difficult to manage. There is conditioning in the showers to help, but it might take a few washes.
Summer (June to August) is the best time to visit Iceland, thanks to the midnight sun and warmer temperatures. Hikers should consider July and August, when all the trails are open. Don't discount winter, though – February, March, September and October are the best time to travel to Iceland for the Northern Lights.
Jeans aren't ideal, even for city activities, because they retain moisture as your legs kick up snow. Cotton clothing isn't suited for Icelandic winter, either, due to it holding moisture when you sweat under your layers. Cotton will grow cold, heavy and wet.
Part of a larger downsizing trend. These closures are not isolated. Since 2023, Iceland has closed more than 20 locations across the UK in response to changing shopping habits, lease issues, and site performance.
Axial Seamount volcano off Oregon Coast now predicted to erupt in 2026. An active underwater volcano off the Oregon Coast that was predicted to erupt in 2025 is now expected to erupt mid-to-late 2026.
The cheapest time to fly to Iceland is during its off-season (January – May). During this time there are fewer tourists so you can expect to find cheap flights to Iceland.
Nature was my on my side because it literally started as I was getting dressed AFTER leaving the blue lagoon. It's a disgusting unfortunate situation we have to go through, but use a tampon and enjoy the lagoon. Highly recommend a menstrual cup!
No volcanic eruption is taking place right now in Iceland. The last one began on July 16th 2025 on the Reykjanes peninsula in southwest Iceland. This was a fissure eruption, meaning that the lava flows affected only the area around the immediate eruption site.
Can you swim in the blue lagoon? The Blue Lagoon experience is designed as a relaxing spa day where you submerge yourself in the bath-warm water and simply unwind. Although you can perhaps swim a couple of leisurely breaststrokes, it's not suitable for vigorous exercise and too shallow to dive into.
What is on the bottom of the Blue Lagoon in Iceland?
Silica—composed of silicon and oxygen—is a constituent compound of lava and merges with geothermal seawater in volcanic aquifers deep underground. When the superheated water reaches the surface and cools, silica molecules are set free, becoming the iconic white mud that is one of Blue Lagoon's hallmarks.
The water temperature is generally between 37°C and 40°C (98-104°F). But owing to variables outside of our control—including the weather and the season—the water temperature sometimes fluctuates beyond this range.
Without adult supervision or societal restrictions, the two navigate the emotional and physical changes of puberty, fall in love, and have a child together before being rescued at the film's end.
In fact, you can always touch the bottom of the lagoon standing up, so it is not like a swimming pool. The milky-blue depths aren't clear either, so you only really want to stick your head under the water to keep warm or perhaps wash off your mud mask.
