On the northwest tip of Long Island in The Bahamas, Cape Santa Maria Beach wraps around Calabash Bay in a four-mile crescent of blindingly white sand. The water is the real show: at your feet it's so shallow and clear you're mostly just looking at sand through a film of water. A few steps out it shifts to pale aqua, then to a vivid turquoise across the bay. Because the whole colour progression happens within one view, it's the kind of beach photographers chase and rarely have to themselves.

The explanation is simple. The same powder-fine sand continues underwater, so the shallow bottom reflects light straight back up. The bay sits on the leeward side of the island, which means the water is usually calm — on still days you can pick out ripples on the sandy bottom from shore. That calm also makes it an easy swim, even for less confident ocean swimmers.

What sets Cape Santa Maria apart from better-known Bahamian beaches is the space. It appears on off-the-beaten-track lists precisely because you can walk for miles and find nothing but palms, pines and your own footprints. The vegetation gives the shoreline a dark green fringe that looks especially good when you turn around and look back from the water. Walk near the waterline where the sand is firmer and the bay's curve keeps changing the view — a stretch that looked straight from your veranda bends away out of sight.

If you want to sleep on this beach, you have exactly one choice: Cape Santa Maria Beach Resort, which has beachfront bungalows and villas steps from the sand. The honest assessment is that it's rustic rather than luxurious — the bungalows in particular need updating. But the trade-off is waking up to that bay, and for travellers whose priority is the beach itself rather than the room, most find it worth it.

Getting there is part of the adventure. Stella Maris is the closest airstrip, about 20 minutes away by taxi; Deadman's Cay, roughly an hour by road, is the alternative. Both are reached by short inter-island flights from Nassau. Long Island rewards a bit of exploring too — head south to Dean's Blue Hole, where pale shallows turn to deep blue within a few swimming strokes. It's one of the world's deepest blue holes and a famous freediving site.

The beach faces west, so the day ends well: the glare softens, the turquoise mellows, and the sunset plays out across the bay. Go for the swimming and the walking in the morning, and stay put in the evening to see the same water in completely different light.

Who is this for? Travellers tired of cruise-crowded strips in Nassau or Exuma who want a proper remote beach with a place to sleep on the sand. It takes two flights and a taxi to get there, and that friction is exactly why it still feels empty.
