Honestly I’d go back to Reykjavik purely to visit the Blue Lagoon. I adore spas, pampering and thermal pools (check out the Budapest thermal baths 101 ), and this is one of the most beautiful of the outdoor baths I’ve visited - unsurprising as it is one of the 25 wonders of the world. Despite the breathtakingly low outdoor temperatures, the water is satisfyingly hot approx, 37-39°C, and its hard not to feel at peace in this place, surrounded by the picturesque snow topped hills and illuminous blue water (they don't call it the 'blue' lagoon for no reason). With free face mud to smother and a swim up bar, it’s easy to spend a whole day in the lagoon with an on-site hotel, restaurant and treatments, so book your tickets and look forward to a day of bliss.
Whilst the transport to the site itself was prebooked in the holiday package, tickets into the lagoon were not included so had to be purchased separately. The blue lagoon is roughly 47km from Reyjavik, and hourly bus transfers are available from Reyjavik centre or the airport, included in some of the entrance ticket prices. You can also arrange taxis and private transfers, whilst car journeys take roughly an hour. Arrive early because despite booking online, the queues are pretty huge as most coach trips to the lagoon all arrive at the same time.
Ticket prices differ between Winter and Summer months whilst generally cheaper in the Winter (classed as 1st Sept – 31st May). The basic package – Standard is €40, only includes the entrance to the lagoon, which may seem like the best idea, however there is a fee for towel hire so may end up more expensive overall. However the Comfort package €55 includes entrance, towel hire, the first drink free (which are at least €5 anyway) and a small kit with travel sizes of the lagoon’s skincare. I would 100% recommend pre-booking tickets, as without this booking you're not guaranteed entry as it is overbooked they will not allow entry.
Add ons: Use of Towel = 5 EURO per person
Use of Bathing Suit = 5 EURO per person
Use of Bathrobe = 10 EURO per person
Slippers = 10 EURO per person
Despite how secure the lockers may be I would definitely recommend NOT bringing any valuables if possible. Upon arrival you will be given an electronic wristband that acts as a lock for your locker, if this doesn't work you're responsible for your own possessions should they be lost or stolen, and as the Blue Lagoon is often VERY busy, it's not worth risking. The wristband also acts as a credit card, as there is a swim up bar in the lagoon where you can purchase drinks, waterproof phone bags and other items. When 'paying' for something, instead you hold your wristband to a detector, which adds it to a tab to be paid upon your departure of the lagoon. There is also a restaurant inside the main building of the Blue lagoon which serves good food, but is pricey (but then again so is everywhere in Iceland).
Entering The Lagoon
Bikinis or swimsuits are acceptable, there's visitors all over the world in the lagoon so feel free to wear whatever you feel comfortable in. This is a great opportunity for photos so remember go-pros or purchase a waterproof bag for phones. The minerals in the water can cause hair to be brittle so I would recommend showering before hand, dampening hair and lathering on lots of the conditioner which is provided in the showers. Not only that they provide large buckets of face-mud around the edges of the lagoon, make the most of this as they sell bottles of it in the spa-store in the main building at an eye-watering price!
The Blue Lagoon is without a doubt one of the most beautiful and relaxing sites I've ever visited whilst travelling and I would return in a heartbeat! For any more details visit: http://www.bluelagoon.com/
