One morning a couple of weeks ago, I visited the Parque Biológico de Gaia, a medium-sized nature reserve in the middle of a forest housing many local species of animals, many of which were found injured in the wild and brought to live out their lives here. There were many baby animals, too, born in captivity. Gaia is on the other side of the Douro River, opposite Oporto, so it was an easy and fun trip. There was a group of school children at the park, too. They were really cute and really excited to pet the donkey.
