A 50-minute Sansa flight from San José is the fastest route to the Osa Peninsula. Heavy rains from May to December wash out unpaved access roads, leaving flights or public boats from Sierpe as the only reliable transport.
Osa Peninsula, Costa Rica
Sansa operates flights one to two times daily from San José to Drake Bay or Puerto Jiménez. The 50-minute route bypasses hours of driving on unpaved roads and drops you near the northern gateway. Small charter planes enforce a strict 30-pound luggage limit per passenger. Pack a lightweight daypack and leave heavy suitcases securely at your gateway hotel. Seats fill up rapidly during the dry season, requiring you to reserve your ticket at least 60 days in advance.
Board a Tracopa bus at the Avenida 10 terminal in San José for the four-hour ride to Sierpe. Walk five minutes from the bus stop to the Oleaje Sereno dock. Public boats depart daily at 11:30 AM and 3:45 PM for the final one-hour coastal crossing to Drake Bay. The boat navigates through mangrove swamps before reaching the ocean, requiring a wet beach landing upon arrival. Pack your electronics in a high-quality waterproof dry sack to prevent water damage from splashing waves.
Drive south from San José to Chacarita, then turn onto Route 223 toward Rincón. Cross the new Paso de la Danta bridge to begin the final 2.5-hour leg on unpaved gravel roads. A 4x4 vehicle is absolutely required to navigate the deep ruts and uneven terrain. This route is only passable during the dry season from January to April. Heavy rains turn the dirt roads into deep mud, making the path completely impassable for any vehicle.
Corcovado National Park lacks dedicated paved parking lots and taxi drop-off zones. Drivers must use a 4x4 vehicle to navigate the final 2.5 hours of unpaved gravel roads past Rincón, passable only during the dry season. The rugged dirt trails and river crossings make the site completely inaccessible for wheelchair users.
