Hi Jon,
My only desire is to share my personal insight of the Azores with as many people as possible. The ultimate dream is to one day see a section for the Azores in a certain famous travel writer's "Portugal" guidebook! You never know ;-)
In two weeks since I returned from this latest Azores trip, my PDF guide has expanded from 26 pages to 79 pages as of today. I am writing a section for the island of Flores which is the 4th island of the Azores I have visited...5 more islands to go. Once Flores is complete, the Azores guide will be about 100 pages long. I knew 23 years ago on the first visit to my wife's ancestral homeland that these islands were, and are, not on the North American radar as vacation destination.
I am 100% confidant that the section for Sao Miguel will have what you are looking for. Specifically to answer your very good question, I have a designed a full day self-walking tour of Ponta Delgada along with maps to guide you. You will be walking through 500 years of history, art, religion, culture, and hopefully much more. With a second day, if you overnight, look over my other 3 full day options I put together to pass a day outside of Ponta Delgada. Maybe it will make you think about returning there for a proper vacation.
All I ask is for you to send me a request at my email address and I will send my PDF guide: (removed)
In the subject line, please type: Azores
And thanks for your kind words of inspiration!
Carl
