🐋 Offshore Fish Species in Costa Rica: What You’ll Catch on Deep Sea Adventures

Costa Rica is known around the world for its legendary offshore fishing. Just a few miles off the Pacific coast, the deep blue waters attract trophy pelagic species year-round, including marlin, sailfish, tuna, and dorado.

Whether you’re launching from Los Sueños Marina in Herradura, Marina Pez Vela in Quepos, or heading out of Tamarindo or Papagayo, you’ll find no shortage of big game fish waiting beyond the drop-off.
