8 tips you NEED to know before visiting Iceland’s Blue Lagoon

It's the destination on the top of everybody's wanderlust list right now and, we can confirm, Iceland's magnificent Blue Lagoon is worth the trip.

The geothermal spa, located in a lava field in Grindavík, just outside the capital Reykjavik, is the ultimate Instagram location; it's been trending for months, flooding the feeds of the world's best travelled bloggers. Not only is it an other-worldly experience to bob about in toasty, blue water as temperatures dip to minus one, it's also a treat for your skin; the mineral-rich water contains silica and sulphur, which can cleanse, strengthen and improve conditions such as psoriasis.

Ready to catch your flight? Here's what you need to know: 1. You can start or finish your trip to Iceland at the Blue Lagoon: The Lagoon is roughly a 21-minute drive from the airport and a 50-minute drive from Reykjavík. If you'd like to visit on your way to or from the airport, there are plenty of buses that can get you there. You can even dump your suitcases at the luggage drop on the way in. 2. You must book online in advance. Sessions fill up fast so buy your tickets in plenty of time, as early as you can. 3. Bring an intensive conditioner or hair masque and put it on while you're in the water. Silica is great for your skin but it is murder on your hair. Bottle blondes can expect a Worzel Gummidge effect that lasts a week. Smart broads bring a water proof swimming hat and load on the conditioner underneath. You'll thank us later. 4. Fill up: If you are not eating at the Lava restaurant, have a big breakfast. The snack bar is cold (and outrageously healthy). 5. Leave your jewellery in your locker (these are operated by electronic wristband) or at your accommodation, the minerals can discolour certain materials. 6. You must shower in your birthday suit. Cleanliness is a fundamental aspect of a geothermal spa experience. Prior to entering Blue Lagoon, a full body shower - sans togs- is absolutely essential. This same aspect of spa culture is found at every pool in Iceland. Private shower cubicles are available in the changing rooms. (Make sure you put your suit back on before venturing into the Lagoon). 7. Bring a waterproof phone or camera cover if you plan on taking a lot of photos. Nipping in and out of the water to put your phone back in your locker in the freezing cold is an ordeal. 8. Hydrate: Bobbing about in the hot pools (the water temperature in the bathing and swimming area of the lagoon averages 37–39°) really takes it out of you. There are spring water fountains near the steam rooms. Visit them regularly (especially if you're hanging out at the Lagoon bar!). Got a Blue Lagoon tip of your own? Let us know on Twitter @Herdotie.
