Costa Rica’s legendary seamounts offer multiple acts in big-game theater. Schools of sailfish provide thrilling action during the offshore run, before the main event unfolds at the deep-water pinnacles. Here, blue marlin hunt in extraordinary numbers, while massive yellowfin tuna crash through bait schools. The pristine conditions and absence of commercial pressure create opportunities for multiple marlin releases, trophy tuna exceeding 200 pounds, and countless sailfish shots make for a single epic day of fishing.
