Our main reason for visiting Angol was to see the nearby Nahuelbuta National Park, a stunning national park, famous for its Araucaria (moneky-puzzle trees). The park is accessible by a 33km dirt road west of Angol. There is public transport from Angol to the park, but it's easier if you have your own car.
We arrived in mid afternoon in the park, giving us time to do only one trek, the hike to Piedra del Aguila, a 1379m lookout over the park. On a clear day you can see both the Pacific and the Andes from this lookout, but there was far too much haze when we visited. We did have a great view, however, of the beautiful Araucaria trees, which are everywhere in the park. It costs 4000 pesos to enter the park, and the hike starts from close to the guardaparque office, 6km west of the park entrance.
Like many Central Valley towns, Angol has an attractive main square which is the heart of the town. We only had time for a quick visit around the town as we spent most of our time in the National Park. The main square seemed like the busiest place in what was a quiet town.
Angol isn't a very touristy town and there were few restaurants to choose from. We walked around the streets in the centre for a while before finding La Rueda, adjacent to Hotel Angol, 1 block east of the main square. It was a popular enough place though there were more people there to drink and watch football than to eat. They offered the usual Chilean meals such as churrasco, lomito, hamburgers and milanesas. The food was good value, though portions weren't too big. The wine was good and also very cheap.
