That was the question my boss asked as I signed off the day before I headed to London. “I want you to do me a favour. Tell me where you swim and tell me which is the best pool”. I already knew that was far too big a question to be answered with a single name but when I got back, having sampled sixteen very different pools during the thirteen days and one evening I’d been away, I realised just how big it was. Big enough for an entire blog post, anyway. Because they were all so different, I’m going to do the pros & cons of each and award it the title of “best for…” rather than attempt to crown any one pool.
Kualaug

Pros: very quiet and private. Almost no one knows it exists. You feel like a local with your own secret pool away from the tourists.
Cons: silty and not overly warm.
Best for… enjoying a silent dip in absolute privacy.
Hvammsvík

Pros: proximity to Reykjavík, beautiful setting, variety of pools of different temperatures, free paddleboards to borrow in good weather in the summer.
Cons: expensive, has been discovered by hordes of tourists.
Best for… quiet winter mornings when no one else is there to disturb the serenity.
Canyon Baths

Pros: only accessible by private tour so pretty quiet. Amazing setting in a narrow canyon.
Cons: only accessible by private tour, so quite expensive and dependent on someone else’s timetable. Lots of steps down from and back up to the minibus. No plumbing, so no toilets or soap in the showers.
Best for… a quiet semi-private bath in an amazing setting
Krauma

Pros: not really known by tourists, variety of pools of different temperatures, view of Europe’s biggest hot spring from the front viewing pool, has a relax room with a log fire.
Cons: expensive, feels like it’s missing a space to swim in.
Best for… feeling like you’ve discovered something the other tourists haven’t spotted yet
Grettislaug

Pros: bathing in a bit of history (it appears in 13th century Saga of Grettir the Strong), mountain views, authentic natural hot pool.
Cons: it’s a long way off the main road and only accessible in summer
Best for… feeling like a saga hero
Hauganes hot tubs

Pros: too small for big tour groups, pretty cheap, great fjord views
Cons: too many children climbing over you, very shallow
Best for… sharing sea views with the locals
Akureyri pool
Pros: cheap, lots of swimming pools, hot pots and slides
Cons: very busy. Not allowed to take photos.
Best for… family fun with every kind of pool you could possibly want
Forest Lagoon

Pros: Set among the trees, conveniently located for Akureyri, free shuttle bus during the day
Cons: had to take out a lot of those trees to get the pool in, very busy, mostly used by people who want to sit along the edges drinking, shuttle bus finishes at 5pm
Best for… drinking in hot water while feeling like you’re forest bathing
Myvatn Nature Baths

Pros: everything you like about the Blue Lagoon but better – cheaper, quieter, wilder, better views
Cons: no electronic wristbands, changing rooms are a bit rustic, a little bit small
Best for… enjoying everything you like about the Blue Lagoon at the other end of the country
Höfn pool
Pros: lively local swimming pool with slides and hot tubs.
Cons: a long way from anywhere else. As with every normal pool, no photos.
Best for… unwinding after a long driving day
Hoffell hot tubs

Pros: amazing glacier views, very quiet because hardly anyone knows about it
Cons: shallow, hot tubs are a bit too hot, dependent on the opening hours of the attached hotel
Best for… soaking in hot water while enjoying the view of the glacier
Kirkjubæjarklaustur pool
Pros: the only pool within at least an hour in each direction, waterfall views, children’s pool is deeper than average with a bit of roof to protect you if you’re there in the pouring rain
Cons: not very exciting. No photos.
Best for… enjoying a very quiet, peaceful authentic pool experience
Vík pool
Pros: hot hot tub, set almost on the beach at Vik
Cons: pools are all a bit small, no photos.
Best for… mingling with the locals in the hot tub
Seljavallalaug

Pros: authentic and characterful, amazing setting among the mountains
Cons: the changing rooms need to be razed to the ground, no toilets or showers, bit hard to find, water not as warm as it could be and a bit grubby because the mountain forms one wall of the pool
Best for… Instagram pictures and experiencing genuine authentic olde-stylee Icelandic pool culture
Hveragerði pool

Pros: large 50m heated outdoor pool, meeting locals in the children’s bathing pool, pretty quiet
Cons: 50m can feel a long way to swim after a busy day
Best for… swimming proper lengths
Laugarvatn Fontana

Pros: likely to be reasonably quiet, direct access to the lake, pools of varying temperature, steam room fed by vent in the earth directly underneath
Cons: steam room smells appalling, everything we know about it is about to be destroyed and rebuilt (although the new pool is probably going to be even better)
Best for… experiencing hot springs up close
Having said that they were all so different, I do have some favourites. In no particular order, I especially like Hvammsvik (in winter only; it’s too busy in summer), the Canyon Baths, Myvatn Nature Baths, Seljavallalaug, Hveragerði pool and Laugarvatn Fontana – and ones that I didn’t go to this summer: Laugardalslaug and Sundhollin in Reykjavik, Viti at Askja (when pH, temperature and tectonic activity allow) and the pools at Eskifjörður and Egilsstaðir.
