Sandra Farms was a lovely way to see a working coffee plantation in Adjuntas. The drive through the mountains to get to the farm was part of the adventure, but while the roads wound up mountain passes, they were in good shape. The last mile or so had some potholes, but I made it with no problems in a compact rental car.
Although coffee is grown, roasted, and widely available in PR, I had never had a really good cup of coffee here. This experience provided the context for why: 90% of the coffee consumed in PR is imported from Jamaica or the DR. While many of the local farms - and certainly Sandra Farms - has high-quality beans grown at elevation and roasted upon harvest, the imported beans are of mixed quality and have the propensity to mildew. In other words, try the coffee here and you'll realize how good PR coffee can be. Buy a bag and you'll remember!
Aside from that, the farm has guanaba, bananas, sugar cane, cacao, and many lovely flowers. It was a great experience.
