Tamarindo Sport Fishing: The Complete Guide to Fishing Charters in Costa Rica

Guanacaste is one of the best places in the world for offshore sport fishing, and Tamarindo puts you just minutes from blue water. Whether you're chasing your first sailfish or a trophy marlin, this guide covers everything you need to know about booking a Tamarindo fishing charter.

What can you catch fishing in Tamarindo?

  • Pacific sailfish, the star of Costa Rica fishing

  • Blue, black and striped marlin

  • Mahi-mahi (dorado)

  • Yellowfin tuna

  • Roosterfish, snapper and wahoo closer to shore

Costa Rica is a catch-and-release country for billfish like sailfish and marlin, which keeps the fishery healthy for years to come.

Best time to go sport fishing in Tamarindo

You can fish all year. Sailfish are most active from about December to April, marlin peak from roughly May to August, and mahi-mahi and tuna show up through much of the year. Your captain will head wherever the fish are biting that week.

Choosing your boat

We offer three boat sizes so you only pay for the space you need, all with a local captain, crew, tackle and drinks:

Half day or full day fishing?

A half-day charter is perfect for families, beginners and anyone short on time. A full-day charter lets you run further offshore to the deeper water where the biggest marlin and tuna live.

Do I need fishing experience?

No. The crew sets the lines, finds the fish and coaches you through the fight, so first-timers and kids catch fish every week.

What to bring

  • Sunscreen, hat and polarized sunglasses

  • Motion sickness medicine if you need it

  • Light layers and a towel

  • A camera for your catch
