There will also be a variety of artificial lures and live bait, depending on the fish you’re targeting. Live bait will be caught ahead of the trip and is always included in the price.
On all trips, you’ll be provided with sandwiches, snacks, fruit, and drinks. On multi-day trips, you’ll also have hot meals prepared. All you need to bring is some sunscreen, sunglasses, a hat.

Of the dozen or so fishing charters that I have done, this is far and away the best. Captain Donald runs an fast paced and efficient operation. He is on top of all the lines and constantly checking and changing lures and bait as the conditions demand. He knows where to find the fish and what to do to catch them. If you are looking for a relaxing sight seeing, swimming, and snorkeling charter then find another boat. If you are looking to catch fish, this is your boat!

Donald and his crew were awesome. True stewards of the sea who not only care about getting you on fish but also care about their impact on something that provides a livelihood for so many in Costa Rica. The highlight of the trip was when my dad was able to reel in a bucket list fish. Hint the fish is in the headline. Thanks Donald and crew for an unforgettable experience.

We have gone on many offshore fishing trips in many different areas/countries, and have owned our own offshore boats as well. Fishing with Donald was great. He was fun and very knowledgeable. We did catch some great fish, but the reason I will definitely fish with him again is the quality of the trip. If you want a great trip out of Golfito, you can go wrong with Dos Mas

Great day with Captain Donald and Andy. Didn't find our intended targets of Rooster and Sailfish, but nonetheless, had great action and tight lines through the day. Tuna were on 🔥. Inshore we also grabbed a nice Blue Jack and Cubera Snapper.
