We already went to fontana and will go to the blue lagoon but we are planing two day trips and would like to see if there are other geothermal baths close by. The first day trip will be Gullfoss and I heard about Hveravellir but cant get specific information (ie is it worth the drive? Is it possible with a small car?). We are also planing a visit to the south shore to see the basalt beach, are there any geothermal baths around or in our way to Reykjavik? We are willing to modify our plans to visit a geothermal bath, so any recommendations for one 2 to max 3 hours from Reykjavik are welcome!
