Flights to the Nicoya Peninsula
In Costa Rica there are two domestic airline companies: Sansa and Nature Air.
In San Jose Sansa has its terminal at the side of the Juan Santamaria International airport (SJO San Jose airport) while Nature Air flies from the Tobias Bolaños Airport in Pavas, a 20 min drive from the international airport.
Check schedules and flight availability:
Both airlines are flying with small aircraft so they have limited space and weight allowance. In general luggage allowance is 25lbs (Sansa) to 30lbs (NatureAir). Bulky items like surfboards or bikes will cost an extra charge and it depends on space and weight availability if they are on the same flight as you.
For traveling to the Southern Nicoya Peninsula, to Montezuma, Santa Teresa and Mal Pais
the nearest airport is in Tambor.
For the beaches of Playa Coyote and San Miguel you fly to Punta Islita.
Unfortunately there aren't flights any more to Samara, as the airstrip in Carrillo has been closed. The next airport is in Nosara.
Northern part of the Nicoya Peninsula:
For visiting Guanacaste and the Northern Nicoya Peninsula travelers can now avoid the long journey via San Jose by flying directly to the Liberia airport. The Daniel Oduber airport (LIR) is located 12 km west of the city of Liberia and receives flights from North American and European cities. From the Liberia airport it's only 45 km to the beach resorts on the Papagayo Peninsula and 70 km to Tamarindo, Playa Conchal and Flamingo.
