FWIW… head the Vieques, rent a small SUV, and hit Chiba beach or the other south coast beaches in the nature reserve area.

Almost empty. The only noise is nature and waves.

Going to Vieques in 2011 was one of the most sublime and wonderful experiences of my life. I never felt like I was at an undiscovered treasure more than I did there: The beaches, the biolumniscent bay, the feral horses, the view over the bay in Esperanza, all of it so breathtaking.
