Tarpon fishing in Costa Rica happens on the Caribbean coast, where the rivers and lagoons from Tortuguero to the Nicaraguan border hold some of the biggest tarpon anywhere. Known locally as sábalo and to anglers as the silver king (Megalops atlanticus), tarpon here average roughly 80 to 100 pounds, and fish over 200 pounds have been landed. This guide covers the best months, where to go, how to fish and the rules you need to know.
Tarpon Fishing in Costa Rica at a Glance
- Where: Caribbean coast: Barra del Colorado, Parismina and Tortuguero, plus Caño Negro inland.
- Best months: late January through early May, and September through early November.
- Size: about 80 to 100 pounds on average, with fish over 200 pounds possible.
- Rules: release tarpon alive, which is standard practice, and get an INCOPESCA sportfishing license.
- Getting there: mostly by boat or small plane; most anglers book a lodge package.
Best Time for Tarpon Fishing in Costa Rica
Tarpon are present year-round, but two windows stand out:
- Late January to early May: the prime season, when tarpon fill the rivers and lagoons around the Río Colorado.
- September to early November: the second peak, when calmer seas often let boats get out past the river mouths to schools rolling just offshore.
- June to August and December: fish are still around, but rain and rough seas can make the best water hard to reach.
On this coast, the weather on a given day matters as much as the month. Calm seas open the river mouths and nearshore water; big surf can keep boats inside. Our guide to the best time to visit Costa Rica by region explains how the Caribbean’s weather differs from the Pacific’s.
Where to Catch Tarpon in Costa Rica
Barra del Colorado
The traditional heart of Costa Rican tarpon fishing. The Río Colorado branches off the Río San Juan, which drains Lake Nicaragua, and the network of rivers, creeks, lagoons and river mouths around Barra gives tarpon a highway between fresh and salt water. It’s remote, inside the Barra del Colorado Wildlife Refuge, and most anglers stay at a fishing lodge. For other places to stay on this coast, see our guide to hotels on the Caribbean coast.
Parismina
South of Tortuguero and north of the port city of Limón, Parismina is known for its river mouth and nearshore fishing. When the ocean lies down, the bite just outside the mouth can be excellent; when the surf is up, boats may not be able to get out at all.
Tortuguero
Better known for sea turtles, Tortuguero also has tarpon and snook in its canals, river mouth and nearby lagoons. It’s the easiest of the three to reach and pairs fishing with a classic Costa Rica wildlife trip. See how to get to Tortuguero.
Caño Negro
In the northern lowlands, the Caño Negro wetlands hold resident tarpon in fresh water, a very different experience from the Caribbean river mouths.
How to Catch Tarpon
Costa Rican tarpon don’t follow the Florida playbook, so lean on your guide. Common approaches:
- Casting plugs and lures to rolling fish in rivers and lagoons, or around drop-offs on sandbars.
- Jigging in deeper water at the river mouths and just offshore when schools are rolling.
- Bump trolling live or dead bait along the bottom.
- Casting spoons to fish working near the surface.
- Fly fishing with a 12- or 13-weight rod and plenty of backing. Ask your lodge ahead of time if it has guides experienced with fly anglers.
Expect to jump far more fish than you land. Tarpon have hard, bony mouths and throw hooks constantly, so a day with many jumps and only a few fish at the boat is normal.
Rules and Responsible Release
- Release every tarpon. Catch-and-release is standard practice in Costa Rica, and lodges and guides expect it. Fishing rules change, so confirm the current INCOPESCA regulations with your lodge before you go.
- Get an INCOPESCA sportfishing license. It costs about $15 for 8 days, $25 for 30 days or $50 for a year, and shore and kayak anglers need a separate license. Most lodges arrange it.
- Keep big fish in the water for photos and revive them until they swim off.
