We also have tried to see the Art Museum in Porlamar - which is closed every time we go. Outside the museum are several sculptures - one is pictured here. Maybe it really will be open next week and we can look inside.
We did take a couple of trips around the island, one by bus, and one with local friends on the island. We saw La Ascension, the capital city of Isla Margarita. It is inland from the coast, and a sleepy town with not many tourists this time of year. It has a lovely cathedral which must be hundreds of years old, with many statues and tableaux of the Passion of Christ.
The local buses are fun to ride; it has taken us quite a while to figure out routes and where to pick them up. The fleet is ancient, along with many of the cars and other vehicles on the island. Here is one bus. The buses are cheap, only one bolivar for fare around Porlamar (about 25 cents U.S.), so we can take a bus just to see where it goes and have an adventure.
