The park has two main entrances. One is in 'Cajanuma Sector' c. 8 km south of Loja where elfin forest and paramo habitats at elevations between c. 2900 and 3500 m can be accessed. The other is in 'Bombuscaro Sector', corresponding to the Bombuscaro River in lower montane forest habitats at elevations from c. 1000 m upwards. There are two alternative entrances without park guards. The 'Romerillos Sector', corresponding to the Jamboé River southeast of the Bombuscaro Sector is also an entrance for gold miners that work inside the park. Another entrance is at Cerro Toledo, east of the Yangana-Valladolid route in the southwestern part of the park.
