Cayo Bolivar

Some places you have to work a little for, and Cayo Bolivar is one of them. A slip of blinding white sand in the middle of the open Caribbean, ringed by reef and nothing else, it lies about 17 nautical miles southeast of San Andres - roughly an hour and a half by boat across deep blue water. For many islanders it is simply the most beautiful place in the whole archipelago, and a day out there feels like being marooned on your own private atoll.

What's out there

Cayo Bolivar is really a small group of low sand cays and a shallow reef complex. There are no hotels, no shops and no crowds - just sandbars that shift with the tide, coconut palms on the larger cay, a small naval and fishing presence, and some of the cleanest water and healthiest coral you will find anywhere near San Andres. The snorkelling straight off the sand is exceptional, with coral gardens, conch, lobster and reef fish in water that glows an almost unreal turquoise.

How the trip works

Because of the distance and the open crossing, Cayo Bolivar is a full-day excursion, not a quick hop, and it only runs when the sea is calm and there are enough people to fill a boat. Historically the trips left once a week - a regular Wednesday departure was the island tradition - but schedules depend on weather and demand, so ask around a day or two ahead. Expect an early start, a picnic-style lunch included on the cay, and a long, sun-drenched day on the water.

Practical tips

• Book ahead: boats don't leave daily; confirm the departure and the weather the day before.
• Bring everything: there are no facilities. Pack plenty of water, sun protection, a hat, a long-sleeve rash top, snacks and any snorkel gear you prefer.
• Sea conditions: the crossing is exposed; if you are prone to seasickness, come prepared. Trips are cancelled in rough weather for good reason.
• Leave no trace: this is pristine, unstaffed reef. Everything you bring must come back with you.

Is it worth it?

If your idea of paradise is a beach bar and a coco loco, Johnny Cay will make you happier. But if you want solitude, spectacular reef and the feeling of sailing off the edge of the map, Cayo Bolivar is the standout day trip on San Andres - the kind of place that ruins ordinary beaches for you afterwards.
