Access to the highland sector of the park is through Cajanuma control, about 10km south of Loja. From here, a dirt road leads 8.5km uphill to the park office and adjacent refugio, which has seven basic cabañas with mattresses and a camping area.
From the refugio, several self-guided trails wend through the cloud forest. More strenuous and wide-ranging is the 5km Los Miradores Loop Trail, a four-hour hike up through the cloud forest and into the páramo (grasslands) – expect strong winds. Another trail that branches off the Miradores leads 14.5km to the beautiful highland lakes of Lagunas de los Compadres: the trail to the lakes is three days' round trip for most hikers.
