I wish I had found this earlier! I come to the islands a lot, and this guide was well worth the cost. We nicknamed the host “Bob”, who was very informative, gave us history lessons and explained local legends, and took us anywhere we needed to go! If you’ve already rented a car, there is no need to also book a tour. “Bob” gives you turn by turn directions, tells you where to stop, explains what you will see and how long it will take, and also makes suggestions about which stops are highly recommended and which stops you can skip if you’’re pressed for time. I highly recommend it!
