Visiting the world-famous Blue Lagoon was one of the optional excursions on my trip to Iceland with an EF Go Ahead Tours group. If you have never visited a geothermal spa before, the Blue Lagoon isn’t just a place to swim, it is a full-body wellness experience with its own unique etiquette, hygiene rules, and surprises.
If you are planning an Iceland itinerary and wondering whether the Blue Lagoon is worth the high ticket price, what the shower rules actually are, and why everyone warns you about hair damage, here is my honest, firsthand guide on what to expect.
Because we visited Iceland in March, the contrast of the crisp freezing air and the warm, milky-blue water made it feel completely surreal.

Is the Blue Lagoon Worth the Money? (Ticket Prices & Inclusions)
The Blue Lagoon is one of Iceland’s most famous tourist attractions, and because of its popularity, it is also one of the most expensive.
Because I took an organized EF Go Ahead Tour, I was able to add this directly as an optional excursion. If you are traveling independently, ticket prices generally range from $70 to $120+ USD per person, depending on the package tier, season, and time of day you book.
Before arriving, I wondered if it would feel like an overpriced tourist trap. However, once I stepped into the warm water surrounded by snow-covered lava rocks, I immediately understood why it lives up to the hype!

Year-Round Water Temperatures
The geothermal water stays between 98F and 104F (37C to 40C) year-round. When we visited in March, thick steam rose off the pale blue water while snow rested on the surrounding volcanic rocks. It honestly felt like stepping onto another planet.

What Is Included with Your Entry Ticket?
Even the basic entry tier provides a complete spa experience. Every standard Comfort Ticket package includes:
Silica Mud Mask: There are several options to choose from, and of course, there are upgrades. You apply the mask right there, let it sit for a few minutes, and wash it off using either the spa water or a cold water faucet located right there by the mask station. I chose the cold water and it felt great!
Complimentary Drink: One free beverage at the swim-up bar. You can also upgrade your drink to a nicer glass of sparkling wine, for example, or multiple other options.
Towel Service: You’ll be provided with a clean towel upon your exit.
Locker Access: You’ll be provided with a wristband that will serve as the key to your locker. Secure all your valuables there and head to the showers.
Shower Facilities: Full shower rooms with shampoo, hair conditioner and body wash.
Is it expensive? Yes.
Is it crowded? Not when visiting during the shoulder season in March!
For a bucket-list destination like Iceland, it is a once-in-a-lifetime experience that fully delivers on its promise.

What Are the Rules for Swimming in Icelandic Geothermal Pools?
Iceland takes public pool hygiene extremely seriously, and the Blue Lagoon is no exception. Before you are permitted to enter the lagoon water, you are strictly required to shower completely naked without a swimsuit.
Understanding Icelandic Pool Hygiene Etiquette
This requirement is standard practice across all public pools and hot springs in Iceland. Locker rooms feature clear signs illustrating the specific body areas you must wash before putting on your swimsuit.
Shower Facilities: Showers are separated by gender. While there are open communal showers, there are also private shower stalls with doors if you prefer complete privacy. Being from the United States, I chose that route, and I did not have to wait at all.
Why the Naked Shower Rule Exists: Unlike public swimming pools in the United States, Icelandic geothermal pools use very little chlorine. Because the water is natural and constantly circulating, keeping the lagoon clean depends entirely on every guest following hygiene rules.
It might feel slightly awkward if you aren’t accustomed to European spa culture, but everyone is doing the same thing. Once you get past the initial shower, it simply becomes a seamless part of the relaxing routine.
The Hair Warning: Why Silica Ruins Your Hair (And How to Protect It)
I have short hair, but take note my friends with long hair. Before stepping into the water, lagoon staff strongly warn visitors to thoroughly coat their hair in conditioner and leave it in while swimming. They also suggest tying long hair up high to keep it out of the water completely. Don’t skip this step.
Why?
The Science Behind the Silica
The Blue Lagoon gets its signature opaque color from a rich combination of silica, algae, and geothermal minerals.
While silica works wonders as a skin exfoliator, it reacts terribly with hair proteins. If your hair gets soaked in the lagoon water, the mineral buildup will leave it feeling extraordinarily stiff, dry, and coarse, almost as if it were coated in superglue or hairspray!
Step-by-Step Hair Protection Tips:
Apply Conditioner Before Entering: Use the free, large conditioner dispensers located in the shower rooms to heavily saturate your hair.
Leave It In: Do not rinse the conditioner out before getting into the lagoon.
Tie It Up: Secure long hair in a high bun using a claw clip or hair tie.
Post-Swim Washing: After exiting the lagoon, wash and condition your hair two to three times in the shower to strip away any residual minerals.
Do You Wear Swimsuits in the Blue Lagoon?
Yes! Swimsuits are mandatory inside the public lagoon area. You’re naked in the showers, but not in the spa.
Swimsuit Choice: Wear a swimsuit you don’t mind putting through rough conditions. The heavy sulfur and silica content in geothermal water can discolor or stiffen delicate fabrics over time. Keep your nice swimsuit for your next cruise or summer vacation.
Robes & Slippers: Included if you upgrade to the Premium or Retreat Spa packages, or available to rent separately.

What Makes the Blue Lagoon So Iconic?
The Blue Lagoon isn’t just a natural hot spring; it is an incredible blend of volcanic landscape, geothermal science, and high-end spa relaxation.
1. Naturally Blue Opaque Mineral Water
That milky blue water comes from silica and minerals reflecting sunlight. It looks striking in photographs, but standing in it in person is even more impressive, especially against that black volcanic rock.
2. Set in a Dramatic Volcanic Lava Field
You are soaking in warm water surrounded by jagged, black moss-covered lava fields in the Reykjanes Peninsula. In March, snow caps the volcanic rocks, creating a dramatic color contrast. Even the walk into the spa is beautiful, with lava rock on both sides of the walkway.
3. Rich Geothermal Minerals
The lagoon is fed by mineral-rich water from the nearby Svartsengi Geothermal Power Plant, where superheated freshwater and seawater combine deep underground. The water is packed with natural silica and sulfur, famous for soothing skin conditions like psoriasis.
4. Full Spa Amenities
Your visit will likely be about 2 hours, which goes fast! You aren’t just standing there in a warm pool though. During your visit, you can:
Apply fresh silica mud masks at the floating mask bar.
Enjoy a smoothie, glass of wine, or local cider at the swim-up bar.
Unwind in the geothermal steam rooms and saunas built directly into the lava rock, which feels especially good if you just got off a long flight.
Explore entire pool, which is larger than I thought! It took awhile just to get from one end to the other.
Essential Visitor Information & Booking Logistics
If you are adding the Blue Lagoon to your self-drive or group tour itinerary, keep these key logistics in mind:
Best Time to Visit: Early morning or late evening slots offer lighter crowds. In winter and early spring, evening visits offer a chance to spot the Northern Lights floating above the steam!
Location & Transfers: Located on the Reykjanes Peninsula, just 20 minutes from Keflavík International Airport (KEF) and 50 minutes from downtown Reykjavík. It makes the ultimate relaxing stop right after landing or before a flight home!
Advance Bookings: Pre-booking online is mandatory. Entry slots sell out days or weeks in advance during peak seasons.
Package Tiers:
Comfort: Includes entry, towel, silica mask, and 1 drink.
Premium: Includes towel, robe, slippers, silica mask + 2 extra masks, 1 drink, and a glass of sparkling wine at Lava Restaurant.
Retreat Spa: Exclusive access to a private indoor/outdoor spa sanctuary.
Blue Lagoon FAQs
How long can you stay at the Blue Lagoon?
There is no maximum time limit on your ticket once you enter, but most visitors find that 2 to 3 hours is the sweet spot. That gives you plenty of time to apply your silica mask, enjoy a drink from the swim-up bar, spend time in the saunas and steam rooms, and relax without getting pruned or dehydrated from the warm geothermal water.
Can you wear glasses or sunglasses in the Blue Lagoon?
You can wear sunglasses or prescription glasses, but be very careful not to submerge them or let them get splashed. The silica in the geothermal water will leave a chalky mineral film on optical lenses that is notoriously difficult to remove and can damage anti-glare coatings. If you need corrective vision, soft daily disposable contact lenses or wearing a secure glasses strap while keeping your head dry is your best bet. I wore my prescription sunglasses, but was careful not to spash.
Can you wear jewelry in the Blue Lagoon?
No, it is strongly recommended to remove all jewelry, especially silver, before entering the lagoon. The natural sulfur content in geothermal water rapidly oxidizes and tarnishes silver, turning it dark brown or black within minutes. Lock your rings, necklaces, watches, and bracelets safely inside your wristband locker.
Is the Blue Lagoon accessible directly from Keflavík Airport?
Yes! Located just 20 minutes from Keflavík International Airport (KEF) and about 50 minutes from downtown Reykjavík, the Blue Lagoon is ideally situated as either the first stop after an overnight flight into Iceland or the final relaxing excursion before flying home. Scheduled transfer buses (like Destination Blue Lagoon) offer convenient direct routes with luggage storage facilities on site.
Final Verdict: Is It Worth Visiting?
While the Blue Lagoon is undeniably one of Iceland’s most touristy spots, it earns its world-class reputation in my book. If you go expecting a rugged, natural wild hot spring, you might be surprised by the commercial spa setup. The setup makes it easier to enter and exit the pool, shower, change and enjoy the area. If you arrive ready for a luxurious, sensory-rich geothermal spa day, it delivers an unforgettable experience.
