Either you travel as individual or group you should visit The Blue Lagoon on the way from or to the airport.

With Miki voucher you can do the transfer to your hotel in 2 parts. Stop at this fascinating natural heated swimming pool in the middle of lava rocks . They have areas to put your luggage as well as what is needed for your bath. Inside you can conveniently buy beer or waterproof camera bags with your wrist band and pay when you leave. Cheers?
