This Park was established on May 14, 1965 through Law N 15574. It is found in the department of Huanuco, province of Leoncio Prado, district of Mariano Damaso Veraun. It has a surface of 18,000 hectares and is made up of a chain of mountains called La Bella Durmiente because its summits have the form of a sleeping lady when seen from the city of Tingo Mara.

The main attractive of this park is the Cave of the Owls which is a huge underground complex beneath "La Bella Durmiente".

You can also visit the thermal baths of "Jacintillo" (sulphurous waters) or the waterfalls of "La Quinceaera". In this park there is a very rich fauna made up of 104 species, 9 fishes, 21 batrachians and reptiles, 39 birds and 36 mammals.
There are big snakes (boas and mantonas) and small snakes called naka nakas (Micrurus sp.). As for birds, we can find guacharos (Steatornis caripensis); a nocturnal bird that nests inside the caves, Gallito de las rocas or tunqui (Rupcola peruviana); the Jungle Condor (Sarcoramphus papa) and the otero (Momotus momota). Mammals are found in the park as well, for example: sachavaca (Tapirus terrestris) the red deer (Mazamo americana), sajino (Tayassu Tajacu), wild cat (Leopardus pardalis) el frailecillo (Saimiri bolivienis) and the pichicho (Saguinus fuscicollis).
