Reykjavik museums and beaches

Today was fairly lazy. I had a late night last night, and today started off cloudy then turned to rain. A good morning for a late breakfast.
The rain stopped a little after 11:00am, so I decided to go to the thermal beach, Nautholsvik. This is about a 10 minute walk from our hotel. At this time of year it is only open at certain times, but midday on a Saturday it's busy! There is a long outdoor hot-tub, and an imported sand beach with a lagoon. Believe it or not, many people swim in the ocean here! I was content to soak in the hot-tub, then go and quickly duck under in the lagoon. (12 degrees apparently) I felt very energized afterwards!
Mom was feeling much better today, so this afternoon we took the bus over to the National Museum. They had an interesting display on the history of Iceland through the ages. We had coffee & shared a slice of vinarterta. Mom's Icelandic friends used to make this cake.
We came back to our hotel for happy hour, then headed over to Perlan for dinner.
It's a lovely setting, a dome on the top of the hill near our hotel, with a great view. We shared fish soup, and lamb chops, a great last dinner in Iceland.
