Cayo Paraiso: A Day on the Sandbar Where the Caribbean Puts on a Show
A crystalline sandbar, teeming reef life, and a mangrove chorus — how to spend a perfect day on Cayo Paraiso.
Punta Rucia, Puerto Plata•By Robert Eric Crews•Water Activities,Boat Charters,Wildlife Nature•March•winter
Continue ReadingThe first thing you notice is how the sea changes mood as you approach: from deep cobalt to a startling, shallow turquoise that seems to glow from below. The speedboat pulls up and the island — Cayo Paraiso, called Cayo Arena on local charts — appears like a pale coin in the water, a strip of sugar-white sand studded with scrub and a few leaning palms. You step off into warm shallows and the ocean meets you with no small amount of personality — a gentle push, a warming hand. Fish scatter in quick mosaic patterns and coral gardens appear like underwater cathedrals. For a few hours the island becomes a microcosm, a perfect Caribbean postcard with a strict ecological guardrail: it's part of a protected area where fishing is restricted so the wildlife is unusually confident.

Photographer's Notes
Shoot in the morning for soft light, use a polarizing filter to cut surface glare, get low on the sandbar for sweeping water reflections, and use an underwater housing or snorkel-point camera for reef close-ups; bracket exposures to keep white sand from blowing out.
