Kirkjusandur beach means church sand beach. Don't be disappointed that there is no church and no sand. We love Kirkjusandur beach. It's right next to the recycled house. There is an amazing view of Reykjavík to your left and (sometimes) snow peaked mountains to your right. There are a couple of picnic tables where you can snack and take time to admire the impressive views. We have been known to bring our bubble machine here and pop bubbles before they blow away. There are a few sheltered dips in the grass where we have read stories together. My kids also like to balance stones into little towers here.. or skim stones out to sea.
