Parque Norte is something of a public parks version of Disneyland lite meets the county fair. It's in the middle of the city and is a bit of an oddity. You pay a couple dollars to get in and can just walk around and have a picnic. Or you can pay $8-10 USD to a punch card or all-you-can ride pass. We opted for the BIG pass.
The ride of the day (IMO) was the log ride (aka Voyage to the Center of the Earth). It had a couple good drops, and you are almost guaranteed to get soaked. Unfortunately none of my photos came out from that ride. There's a really good Hall of Mirrors we hit at the get-go as well.
Next stop was the dinosaur jungle boat-ride. They loves them some animatronics down here.
Because we did the all-you-can ride pass we did the airplane as well. This is a "grandma" ride that consists of sitting in an air-conditioned airplane while a simulated flight over Cartegena is shown via LCD screens in the windows. And the seats randomly move. Great for a hot day, but not much else.
The 3D (5D) experiences use old 3D technology that made me a bit sick to my stomach. My advice is to pass on these.
Then we got to the roller-coaster. They warn you to keep your hands inside at all times. Heed the warnings. There are a couple dips where your hands will be taken off if your arms are raised. Also, I would not advise riding this coaster if you are over 6 feet tall for the same reason, except it would be your head. The coaster starts with a solid push by the attendants. Then it is a bit of a Rube Goldberg mousetrap ride. Fun, but a bit scary.
The hit of the day was the Super Slide. The kids must have done it 20 times. It is pretty big, but there is nothing "Polar" about it on a hot day.
