Porto was great! We could easily have spent several more days there visiting museums and doing tourist things. Since we only had two days, we bought tickets for a couple of double-decker bus tours. The first one took us to the historical buildings and monuments and ended across the river in Vila Nova de Gaia where the port companies have their warehouses and tasting rooms. Our visit to Taylor's lodge has its own photo page.
The second tour took us back down the river Douro to the Atlantic coast and near the area where Solstice was docked. This gave us a better perspective on our neighborhood. If we had stayed more days, we could have put this knowledge to good use. Leixões, where we were docked, also has its own photo page.
