As anyone who has dropped in on the more accessible parts of Cuba's coastline will tell you, the problem with most beaches worth their weight in paradise is that they're often filled with sunning tourists, holiday-making locals, or both. Unless, that is, you can get out along the Atlantic shores of Cayo Sabinal to one of Cuba's best kept secrets, Playa Los Pinos.
First off, the real adventure is in getting there. About 25km up the coast from Playa Santa Lucía, Cayo Sabinal is a long cay that parallels mainland Cuba. It's not often attempted by travelers because there is no public transportation out this way, and the last stretch of what might be called a "roadway" is composed of infamously rough terrain. In fact, most visitors still come via boat from Santa Lucia, and the daily numbers are small.
If you're self-driving, the dirt track that stretches to its northern end, where you'll find Playa Los Pinos, cuts through miles of off-track woodland and marshes that teem with deer, wild boar, and a plethora of butterfly species. Keep an eye out for the Playa Los Pinos signpost; the fine, white sand spotted with tufts of grass, the beckoning sea, and most of all, the sounds of a world without cars or people. Bring some snorkeling gear to explore the reefs far out along the western end of the beach, take a barefoot hike along miles of near-deserted coastline, or just spend the day alternating between swimming and relaxing on the shore. As remote beaches in Cuba go, this one's still a fantastic find.
