Our transportation was excellent in both directions. On the way back to Reykjavik, our driver dropped us off at a bus stop that was close to our accommodation rather than the central bus station, which saved some time. The lagoon was not crowded on the day we went, a Friday. Check in was quick. Only a few minutes in line. Using the lockers was a bit challenging since no instructions were provided. We had to watch someone else to figure it out. The lagoon was smaller than I expected, but nice and clean and relaxing. We stayed about 90 minutes before returning to the city.

Well worth a visit the only negative point was we paid premium tickets to use the mud masks and noticed everyone was, didn't really use the robes ( only walking from the pool to the charging room about 10 steps) but overall a really good day out transfer was brilliant even dropped us back to our hotel instead of a 20 minute walk. Just wish we had paid for the cheaper option.

Walked from Downtown Reykjavík to the bus terminal, only 20mins and great to see the city. Very easy walk, got to the bus terminal, bus arrived 15mins before the departure time, they checked the ticket on my app. Easy peasy. Left on time, got there and was given a paper with all the return bus times. Spent 4hrs at the blue lagoon, and upon boarding the bus again, the driver asked everyone where they wanted to go and arranged to stop at the bus stop right by our hotel which was very nice of him. Highly recommend you book this!
