One Cruise Critic user suggested using Google to search for the best spots in the local area.
To do this, simply type the port name into the search bar, followed by the term « sightseeing » and see what comes up.
The cruiser said: « There might be something of really special interest to you… or not. If not, then plan to wander around the town or head to a nice beach or find a self-guided walking tour.
« Also, look at the cruise-sponsored ‘excursions’ and where they go/what they see. Those may include some of the more popular sightseeing spots. »
