I had an excellent time touring this area and looking at the beautiful scenery. Our tour guide gave us a very good background about the islands and their many stories.

Boldt Castle is well worth the tour ! We went up in the early 1980's and in the late 1990's. The amount of work they have done to finish the castle is immense. Still a work in progress, but beautiful castle, boathouse and surrounding grounds

Stopped here on our boat tour. Covered area to eat your packed meal or the food purchased at the food bar. Other seating available along the docking area. Clean restrooms and a spectacular view.

I don't know that there is much open down by the water in Alexandria Bay early in the morning. I imagine there might be even fewer options in September. It might be better to pack a lunch the night before.
