The Maritza Biological Station is located at the foot of Volcán Orosí at 600m elevation in a transition zone between deciduous dry forest and evergreen submontane rainforest. From the Panamerican hiway, it's about 17 km to the station on a 4WD road.

The road is passable year round although it crosses several seasonal streams.

The road traverses regenerating areas of lowland dry forest as it climbs gently toward the volcanos.

Volcán Orosí completely free of clouds, a rare sight except during peak dry season. The Maritza station is visible to the right near the bottom of the slope, under the broad "saddle".

There are numerous streams that drain the slopes of Volcán Orosí and Volcán Cacao within walking distance of the research station. These watersheds have been studied intensively by the Stroud Water Research Center for over two decades.

There is a well-maintained system of trails around the station, including one that climbs 500m to the Cacao Biological Station.

Pacific slope rainforest transitions to cloud forest along these trails.
