Modern four-star hotel in the geothermal town of Hveragerði, 45 minutes from Reykjavík and at the start of the Golden Circle and the south coast. Spacious rooms with geothermal shower, suites with living area, 24-hour reception, free parking. On the ground floor is the food hall Mathöll Suðurlands with several restaurants, a café, cocktail bar and ice cream parlour.
The hike into the Reykjadalur valley to the hot river starts in the town – an hour uphill, then a bathe in the stream.
I almost always book through Booking.com – for the free cancellation and the genuine reviews.
