On Puerto Rico, horses roam the farms, the mountains, the town centers—and also the beaches. A couples' horse ride at sunset is a perfect way to kiss the day good-bye. With Tropical Trail Rides, in the northwestern municipality of Isabela, you can take a two-hour ride through the forest and by the beach as the sun sinks down toward the water. Make sure you take the opportunity to break for a hike or a swim along the way. On the north side of the island in Manatí, Kerry’s Horses designs personalized sunset rides by the beach or through nature reserves.
