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.

Full Day trip – Inshore
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!

3/4 Day trip -Offshore
We had a great time fishing with Oscar. It is the slow season for fishing so we didn’t expect to catch a whole lot, but it was exciting when my husband caught a sail fish! And almost got a marlin. Great experience! P.s. don’t be Like me and not bring Dramamine or you’ll be puking off the side of the boat if you get motion sickness😂 Overall though, definitely will be coming back again. Thanks Oscar!

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.
