Blue Lagoon Iceland - Worth it or not?

The last I saw in the news was that the Blue Lagoon was closed due to the close by erupting volcano.

As of today it is open and they are monitoring things closely. We're not going to Iceland until mid-August and will keep checking. But I'm interested in whether people think the Blue Lagoon is worth going to or not. Thanks in advance.

The thing about the way you phrase your question is that you're asking for each
person's individual opinion and you're not likely to get too much info on why that
is their opinion.

I have not been to BL, but I have been to a local aquatic facility in an Icelandic town
(Hveragerdi) and I can say that for a fraction of the price you get a somewhat downscale
but locally authentic experience. That is worth it for me more than BL.

Plus, there are multiple package options and prices at BL and that factors into an
evaluation of worth.

If you want the spa and pampering experience, then I say just go for it if they are open
when you go.

I went to the Blue Lagoon the morning before my flight home and it was worth it to me. It was a nice way to relax before the flight and it was easy to get to the airport. If I’d had more time in Iceland, I might have tried a less tourist-oriented place.

I can't say if it is worth it for you or not, but I can share my experiences. We have been to the BL several times ,as well as many others all over country. Also the local pools, and natural hot springs. On every trip we try to do as many of these as we can. That said, we enjoy the BL. We do go right when they open so that there are fewer people. We have never done the spa there or anything, just the regular BL with the masks. IMO, you can't go wrong with the BL or any other place to soak. If it looks like it interests you, then book it. If you share the rest of your itinerary, I can give input on options in other areas as well, if you want.

There's a section in my 2023 TR that is headed Thermal Pools. We looked at Blue Lagoon, and used two others, on the Golden Circle.

We went in 2015 and it was the perfect way to get over jet lag after our overnight flight from Seattle. I believe the flight landed around 7.00 am, we got breakfast at the airport cafe when it opened, caught the first bus from the airport to the Blue Lagoon and just floated, relaxed and napped in the lounge until we could check in to the Northern Lights hotel whose car picked us up.

For what it’s worth, I decided to skip, on this trip anyway. We will go to Laugarvatn Fontana instead. We’ve not been to Iceland yet, leaving in less than 2 months, so I have no first hand knowledge of the post decision regret (or confirmation bias), but understand the internal debate of making the decision!

Good Luck!

We’ve only been to Iceland once (Aug 2023). We added on three days at the end of a cruise from Norway to Iceland. Spending a few hours at the Blue Lagoon was fun and relaxing. I’d do it again. Have a good trip!
