Half Day Trip – Inshore Fishing AM
My wife and I booked a charter with Oscar at Osmak Fishing Charters with one goal in mind: to catch a roosterfish. Oscar not only delivered but put me on an ABSOLUTE TROPHY roosterfish! He was incredibly helpful, making sure we had everything we needed throughout the trip. From water, juice, soda, and beer to fresh fruits and snacks, he had us covered. Both Oscar and his mate were super friendly, easy to talk to, and made the entire experience enjoyable and stress-free. I 100% recommend fishing with Oscar and his crew to anyone looking to fish while in Costa Rica. PURA VIDA!!

Full Day trip – Offshore
The captain and his mate were incredibly kind to us and very helpful for us that were new to sport fishing. Very quickly, they led us onto several sailfish, of which we landed 2 of them. Unfortunately for our trip, we did not land any tuna, but it was definitely not for lack of trying. The captain and his hand worked very hard trying different places, changing tactics, and racing around to new hotspots. I would absolutely recommend them to anyone looking for an experienced and hardworking crew.

Half Day Trip – Inshore Fishing AM
Excellent day out with Oscar. After fishing for live bait, which took about one hour, we got on the fish almost immediately. We were complete novices but caught two Jacks and two Rooster fish, plus plenty that got away!!! We fished further down the coast away from the marina, towards the national park with empty beaches. A fun morning out with my son who was ecstatic on catching two big fish.

Half Day Trip – Inshore Fishing AM
Wonderful experience and it was because the crew really knew what they were doing. It ended up being a bit of mix. Offshore at the green season current break where we had dorado and tuna, closer to shore with jack and runner. Everyone got a fish or two. One of the highlights was rescuing a turtle wrapped up in fishing stuff. I said let's help it and the captain didn't hesitate. The ocean was quite big that day but you could see the experience of the crew on show. I will use this boat again.

Great trip, with my 15 year old daughter and 13 old son, we all enjoyed the fishing and Oscar and crew are great and always making sure everything was taking care off. We landed a big yellow fin Tuna and a Sailfish, we had a bite for a second one. We all enjoyed the experience and would definitely recommend Oscar. Pura Vida!
