Arecibo Lighthouse and Historical Park

This is a wonderful place to take the kids for an educational visit. Immediately inside the gate is a model of a Taino village, then you can follow the trail up to the lighthouse. Along the way there are pens with turtles and other animals, and you will probably see iguanas wandering the grounds.
Visit the lighthouse, and then head to the aquarium and museum to learn a little more about life on the sea. There are mock-ups of ships on which visitors can climb and take pictures, and a recreational area with playground equipment and a small water park. There are also food vendors on site, so you can make a day of it. The hours are Monday to Friday, 9 a.m. to 6 p.m. and Saturday and Sunday 10 a.m. to 7 p.m.
