Most people plan Minho & Viana do Castelo around whatever comes up first when they search it.

We created a 3-day route through Minho & Viana do Castelo, kept tight enough to actually enjoy it, built around what the same basilica staircase photo doesn't show you.

Everyone comes home from Minho & Viana do Castelo with the same photos. This is how you don't. It's completely free to download, so the only real risk is not opening it before your trip's already planned.
