The only tropical rainforest in the United States forest system sits less than an hour east of the villa, and the change is immediate. You leave the coast road, climb into cloud, and the air turns green and cool. La Coca Falls drops eighty-five feet beside the main road at kilometer 8.1, close enough that you can stand at the base within a minute of parking. Further up, the Yokahú observation tower gives you the canopy stretching to the sea, and the short trail to Juan Diego Falls ends at a pool that is cold, clear and shallow enough to stand in. Reserve your entry online before you go, as vehicle access to the upper forest is timed and slots sell out in high season. Go early. Mornings are clearer, cooler and quieter, and rain is likelier after lunch, though a shower here is part of the point. Wear shoes with grip, since the stone steps stay wet all year, and bring water and a dry bag for phones. Plan on half a day door to door, or make it a full one by carrying on to Luquillo for lunch at the kiosks on the way home. Michael can help you time the drive around traffic.
