Getting there & away
Buses to San Isidro depart from the soccer field at 7am and 4pm (US$1, two hours). Any of the hotels can call a taxi for you.
Driving from San Isidro, head south on the Interamericana and cross the Río San Isidro at the southern end of town. About 500m further cross the unsigned Río Jilguero and take the first, steep turn up to the left, about 300m beyond the Jilguero. Note that this turnoff is not marked.
The ranger station is about 18km up this road from the Interamericana. The road is paved as far as Rivas but beyond that it is steep and graveled. It is passable to ordinary cars in the dry season, but a 4WD is recommended. If you are driving past the village of San Gerardo de Rivas, to Albergue Urán or to Cloudbridge Nature Preserve, you will need a 4WD.
