I’ve been to Iceland, but only barely. Flying back to Boston from Glasgow on Iceland Air, there is a 5 hour connection in Reykjavik Airport. This is more than enough time to buy a return shuttle ticket from the airport to the Blue Lagoon, rent a swimsuit and towel (or think ahead and bring your own) and get in the water.
If you ever find yourself with a similarly lengthy connection, I would highly reccommend doing this. The airport is tiny, and as only one airline is flying in and out, it will only take a moment for you to get back through security to check in for your connection.over 6 years ago
