This was a perfect itinerary, allowing us to see all the major sights of the Snæfellsnes Peninsula in one day, and even visit the recently famous Red House, which is accessible without a car. Our guide, Joyce, from China, was very friendly and shared a lot of information and stories about Iceland and the Snæfellsnes Peninsula, greatly enriching our trip. Overall, I highly recommend this itinerary.
