Audio Guide of Angeles, Biobío

The park is open year-round, from 9:00 a.m. to 6:00 p.m. It is reached from Concepción via Route 160 toward Cabrero. After arriving in the town of Yumbel, follow the signs to the lagoon (an additional 45 minutes by car). Check updated routes at Sernatur Biobío.

Access is free. It is a natural area with no entrance charge, but visitors are encouraged to help with its upkeep by not leaving waste behind. For private guided excursions, check with local operators such as Turistel.

A full visit takes between 2 and 3 hours, including walking the trails (3 km in total) and time for photographs. The main circuit is of moderate difficulty, ideal for stopping at viewpoints.

The name reflects the intense green color of its waters, caused by minerals and algae. It is an important ecological reserve where you can spot birds such as coots and black-necked swans. More information at CONAF.

We recommend spring and summer (September to March), when the water is warmer and the vegetation is in bloom. Avoid rainy days, as the trails become slippery, and choose morning hours to avoid the strongest heat.

The terrain is uneven, with dirt and stone trails, and it is not adapted for wheelchairs. It is possible to reach the first viewpoint partially by vehicle. Contact the Yumbel Tourism Department for alternatives.

Nearby highlights include Salto el León (a 25 m waterfall), Termas de Chillán (90 km away), and Callaqui Volcano. In Yumbel, visit the Sanctuary of Saint Sebastian. More options at Biobío Tourist Guide.

We recommend: non-slip footwear, sunscreen, a hat, and water. Bring binoculars for birdwatching. Campfires and swimming are prohibited. To report emergencies, contact Yumbel Police (+56 41 222 1396).
