Living in New York City for ten years taught me to always look up—skyscrapers, stars between buildings, opportunities in every direction. But in Belize, I learned what it means to look down—into something vast, mysterious, and quiet. The day I flew out to the Great Blue Hole, I didn’t know it would shift something in me. But it did.

The flight over was half the magic. From above, the Blue Hole looked like a perfect sapphire dropped into the Caribbean—round, endless, and impossibly deep. I remember thinking, “How does nature even do this?” That one image—the navy blue ringed by bright turquoise—was enough to make my heart skip. But seeing it from the boat was something else entirely. The water was so clear, it felt like floating above another world.

I snorkeled along the rim, tracing the edge where the reef drops suddenly into darkness. Just beyond the coral, the sea fell away into pure blue silence. Even from the surface, you could sense the depth. Divers suited up and descended into the sinkhole’s secret chambers, but I was content near the top—letting the sunlight ripple through the water, watching schools of fish shimmer just out of reach.

Afterward, we stopped on Half Moon Caye for a beachside lunch—grilled fish, coconut rice, and chilled watermelon, served under palm trees with sand between our toes. I sat there with salt in my hair, toes dug into warm sand, and thought, “This is the kind of silence I never get in the city.”
