A CONAF reserve dating from 1907, which makes it the oldest tract of Protected Forest not just in Chile but in the whole of Latin America. It is located 75 km from Collipulli on the road to Pemehue and covers an area of 16,625 hectares.

In the Reserva Nacional de Malleco you can enjoy excellent fishing. It is also a great spot for fans of wildlife photography because, if you are lucky, you may get a view of a condor.

Meanwhile, in the extreme east of the municipal area, you will find the Pemehue hot springs, with alkaline isothermal waters that flow out at 37°C.

In this area there are other isolated springs with slightly lower temperatures than at the Termas de Pemehue, but they have waters with similar qualities.
