The mineral water is incredible for your skin but brutal on anything you're already wearing. I slathered on my usual moisturizer before getting in and regretted it within minutes. These held up and actually made my skin feel better after.













Nobody warned me how badly the silica clings to hair. I watched a woman at the changing room try to comb through her tangled mess for twenty minutes. Don't be that person.













I overthought this so badly. Packed a full tote bag my first time when all I really needed fit in a small dry bag. Here's the streamlined version that got me from parking lot to pool in five minutes.













Showing up without a plan nearly ruined the experience. My first visit was shoulder-to-shoulder tourists taking selfies. The second time I adjusted my timing and it felt like a completely different place.













The on-site restaurant is solid but pricey. Grindavik is only a few minutes away and has spots that locals actually eat at. I made the mistake of eating only at the lagoon my first trip and missed out.













The Reykjanes Peninsula is packed with volcanic landscapes most tourists skip entirely. I almost drove straight back to Reykjavik and would have missed some of the most dramatic scenery I've ever seen.













Small stuff that made the difference between a smooth day and a frustrating one. Most of these I threw in my bag last minute and ended up grateful.
