SANSA and Nature Air are the providers for air travel to Tortuguero. 

The schedule depends on how busy the season is.  They typically fly in once per morning, and every once in a while in the afternoon.

Victor Barrantes, a bilingual local guide, is the Sansa representative in the village (709-8055). He can be found at the airport upon arrival of both Sansa and Nature Air flights if you need a ride to the village.  He also has an office right in town.

View from plane directly over the Village of Tortuguero, heading toward the airstrip.  You can see Tortuguero Hill (the highest point in Costa Rica on the Atlantic coast) off in the distance.
