Only 25 minutes from Eyrarbakki, past the town of Selfoss, is the volcanic crater Kerið. If you are headed to Þingvellir (Thingvellir), Gullfoss, Geysir, or Laugarvatn, you will pass by this place on your way, and it’s well worth the stop. Beautiful winter or summer, there is a walking path both around the rim and around the lake at the bottom.
