Why there’s no “book now” button on this site.
Automated calendars lie.
A booking widget doesn’t know the moon phase, the bait movement, or that a front is about to push the marlin onto the shelf three days early. Captain Mike does — and he builds your run around it.
Online travel agents take 15–20% off the top of every booking. That’s money that should be in the boat’s fuel and tackle, not a platform’s margin. Book direct and it stays where it belongs.

The Southern Zone Advantage
PROTECTED LAUNCH. UNTOUCHED WATERS. ZERO FLEET CONGESTION.
“Launching out of Golfito gives us flat-calm departures inside Golfo Dulce before we push out past Matapalo. Whether we’re working inshore structure or running out to the offshore seamounts, you’re fishing untouched waters without 40-boat tourist fleets crossing your lines.”
That’s more lines in the water, more shots at fish, and less of your day burned getting to where the trip actually starts.

Frequently Asked Questions
You cannot ship fish commercially out of Costa Rica, but you can pack frozen fillets in your checked baggage for the flight home. Airport security and agricultural police perform routine inspections via the Servicio Fitosanitario del Estado (SFE). Our crew cleans, vacuum-seals, and bags your catch dockside.
Yes, Costa Rica law requires every angler aged 18+ to hold a valid fishing license issued by INCOPESCA ($24/year). We recommend securing yours online in advance.
Fishing here never stops. Unlike northern tourist hubs, the waters off Golfito produce sportfishing 12 months a year. Seasonal changes switch the primary target profile.
Third-party agents charge 15-20% commissions. Capt. Mike has guided the Osa Peninsula for 20+ years. Direct booking ensures 100% of your funds go into fuel, tackle, and preparation.
The dry season (December–April) brings calm seas and heavy Sailfish runs. The green season pushes rich river plumes out of Golfo Dulce, creating massive debris lines where monster Marlin hunt aggressively.
Offshore runs target Blue Marlin, Sailfish, Yellowfin Tuna, Mahi-Mahi, and Wahoo. Inshore runs target trophy Roosterfish, Cubera Snapper, and Grouper along the rocky reefs.
While northern ports get blown out by Papagayo trade winds, our Southern Zone position stays protected. Our 28′ TwinVee catamaran hull offers exceptional stability.
Yes. Our crew provides hands-on coaching, rigging instruction, and fighting technique tailored to your group’s experience level.
Direct bookings connect you straight to Captain Mike’s personal phone. You get real-world fishing intelligence without corporate middlemen.
A standard 20% deposit holds your calendar slot, with balance settled on the day of departure. Peak season dates lock months in advance.
100% of Sailfish and Marlin are released alive. Under INCOPESCA Regulations and IGFA ethics, we use non-offset circle hooks and de-hook fish in the water.
Full-day runs (8+ hours) are required to reach the continental shelf and seamounts for pelagic species. Half-day runs are for targeted inshore reef structures.
Our boat comes rigged with tournament-grade Penn and Shimano tackle. Pack polarized sunglasses, non-marking deck shoes, high-SPF sunscreen, camera gear, and cash for gratuity.
Standard dock etiquette in Costa Rica is 15% to 20% of the total charter price, rewarding the crew’s hard physical labor, bait rigging, and angler instruction.
Take motion sickness medication the night before and the morning of departure. Emergency protocols align with Cruz Roja Costarricense guidance.
Shore fishing carries serious hazards, including heavy surf and wild American crocodiles exceeding 15 feet in protected zones governed by SINAC. Fishing aboard our TwinVee ensures maximum safety and higher yield.
Tarpon and Snook are targeted on the Caribbean coast and northern river networks. On the Pacific Osa coast, we focus on Roosterfish, Cubera Snapper, Marlin, and Tuna.
Shared charters are rarely feasible due to conflicting dates and preferences. All Colio charters are 100% private runs tailored exclusively to your group.
