Direct answer
The Blue Lagoon (Iceland) is a geothermal spa requiring advance tickets and basic preparation: book timed-entry in advance, follow on-site rules, arrive early/late to avoid crowds, and bring swimwear and a waterproof bag.
Visa / entry requirements
- Entry to Iceland: Check whether you need a Schengen visa. Citizens of many countries can enter visa-free for short stays; others must apply for a Schengen visa in advance. Confirm current rules with your nearest Icelandic embassy/consulate.
- Blue Lagoon entry: The lagoon itself requires a paid, timed-entry reservation (ticket). Tickets are not a visa/immigration document—you still must meet Iceland’s border entry rules.
Best time to visit
- Year-round destination: winter (Nov–Mar) for northern lights and atmospheric steam; summer (Jun–Aug) for milder weather and longer daylight.
- Avoid peak crowds: early morning (opening) or late evening sessions are less crowded. Midday and weekends are busiest.
Safety tips
- Water temperature: pools vary ~36–40°C (97–104°F). If you have cardiovascular issues, pregnancy, or other health concerns, consult a doctor first.
- Slippery surfaces: walk carefully on wet, often algae-slick paths and steps.
- Hydration: the warm water can dehydrate—drink water before/after and limit soak time to 20–40 minutes at a stretch.
- Alcohol: consumable on-site in moderation, but avoid heavy drinking while bathing.
- Skin sensitivity: silica mud and minerals can dry or irritate sensitive skin—shower and moisturize after.
Local customs and etiquette
- Shower before entering: mandatory nude showering in the locker-room (use of soap/shampoo). Follow staff instructions.
- Swimwear: required in the pools. Bring your own swimsuit; rental options exist.
- Quiet, respectful atmosphere: keep voices low, respect personal space and photos rules in certain areas.
Currency and payments
- Currency: Icelandic króna (ISK). Major cards (Visa, Mastercard) are widely accepted; you rarely need cash.
- Tipping: not required; service charges are included in prices.
Transportation
- From Reykjavík: about 45–50 minutes by car; many hotels and operators offer direct transfers and combo tours. Book transfers in advance during high season.
- From Keflavík Airport: roughly 20 minutes by car; shuttle options and private transfers available.
- Driving: winter driving can be challenging—check road conditions (road.is) and weather (vedur.is). Rent a car with appropriate tires and insurance if self-driving.
Must-know tips and practical advice
- Book early: tickets often sell out, especially at popular times or for premium packages (e.g., Comfort, Premium).
- Select the right package: Comfort includes towel and drink; Premium adds a robe, slippers, and silica mud mask—compare to decide what you’ll use.
- Bring essentials: swimsuit, waterproof phone case or leave electronics in lockers, hair tie (silica can mat hair), flip-flops for locker areas.
- Hair care: silica can stiffen hair—apply conditioner before entering or use the provided silica mud only on face/body, not hair. Use the in-house conditioner after showering.
- Photography: allowed in public areas but be respectful of privacy. Drones are restricted—check local regulations and Blue Lagoon rules.
- Combining activities: many visitors combine the Blue Lagoon with the Reykjanes Peninsula, Golden Circle, or airport timing—plan logistics so you’re not rushed for flights.
- Medical needs: the water is generally safe, but if you have open wounds, skin conditions, or implanted medical devices, ask staff or your doctor before entry.
Local insight
- Consider visiting the newer, less crowded options (e.g., Sky Lagoon in Reykjavík or other geothermal pools) if you want a quieter or cheaper alternative.
- Sunset/winter visits are magical with steam and possible northern lights—book a late slot and keep an eye on aurora forecasts.
