We arrived early, but we could not enter until 9:45. Our "Comfort Package" included a towel, a silica mask, and one drink of your choice. They give you a fancy electronic wristband which locks and opens your locker (confusing, but they have people that help you figure it out) and tracks any purchases you make. The locker area was much cleaner and nicer than the Nature Baths at Myvatn. They have private shower areas (you are expected to totally shower without a swimsuit before entering). They also have an inside ramp that goes into the pool, so you don't have to run outside in the cold!
The pool was built with black volcanic rocks and is quite large with a lot of alcoves to wander and relax. Although there were lots of people in the pool, it never felt overly crowded. The geothermal water really is blue, warm, and steamy. The water is silica-rich and feels very relaxing.
We tried out the silica masks - the look is a bit scary!
By the way, I used this waterproof case for my phone. It worked fine, although some pictures got a bit blurry when shot through the plastic.
We stayed in the water for a couple of hours, then headed back to the locker room. The locker room has Blue Lagoon special shampoo, conditioner, and lotion - use it, because it is really expensive if you want to buy it in their store. They also have hair driers and bags for your wet swimsuit.
We headed for the airport, returned our rental car, and then got checked in for our flight. We had a two-hour flight delay, so we ate some lunch and then just hung out in the airport. Our flight departure actually was on a lower level where there wasn't much seating. People got into a long line before the flight is ready to board. Our IcelandAir flight unexpectedly had chartered an airplane from another airline - we ended up in different seats than we had booked. It was pretty old - my tray table was wonky and the entertainment system didn't work. But it got us home safely. We spent the night in Toronto at the Delta Marriott Hotel near the airport, taking advantage of their park, stay, and fly service. The next day we drove back home
Iceland was amazing! If you ever have the chance to visit, GO!
