  • star rating  We had the most amazing 2 days! We took a sunset cruise one the first evenings we arrived in Tamarindo. The views were amazing, the boat was beautiful and comfortable, and the crew was extremely attentive.

    The second day we went fishing!! Wow!! After a short ride out, we spent the next few hours catching huge fish after huge fish! We caught 2 marlin, 3 sailfish and hooked a wahoo! It felt like every time we released one we had another one hooked right after it! The crew was incredible at helping and kept this beautiful boat looking immaculate. It was such an amazing experience. I would highly recommend it to anyone I know!
