The morning light on Punta Sam slices across a glassy channel as guides load snorkel gear into a low-profile boat. You can feel the ocean's pull — warm, clear, and busy with life — and within an hour the captain radios a patch of moving shadows below. Eyes on the surface, fins ready, you slip in two at a time to meet the planet’s largest fish.
