Gateway to the Osa Peninsula and ancient stone sphere culture.
Palmar Sur is a small agricultural town in the Térraba-Sierpe region of southern Costa Rica, situated along the Pan-American Highway near the mouth of the Río Térraba. It serves primarily as a transit hub for travelers heading to the Osa Peninsula, Drake Bay, and Corcovado National Park, making it a practical overnight stop rather than a destination in itself.
The town is historically significant as the site of large pre-Columbian stone spheres crafted by the Diquís culture, some of which remain visible on former banana plantation lands. The surrounding wetlands and mangroves of the Térraba-Sierpe National Wetland offer exceptional wildlife and birdwatching opportunities just minutes from town.

Getting around: Palmar Sur is best navigated on foot within the town center, as it is compact and walkable. Interregional buses connect Palmar Norte (across the river) to San José and to southern towns like Ciudad Cortés and Golfito. Taxis are readily available and affordable for short trips between Palmar Norte and Palmar Sur. There is no rideshare service; local taxis are the standard option for reaching the river docks or Finca 6.
Best time: December through April, the dry season, offers the most reliable weather and easiest access to surrounding nature reserves and boat tours.
Local food: Try fresh river fish dishes, gallo pinto with locally grown rice, and tropical fruits sold at roadside stands reflecting the area's rich agricultural heritage.
