Set high in the mountains of Cayey near the Aibonito border, this exceptional 100+ acre estate offers a rare combination of seclusion, natural beauty, security, and modern comfort—just one hour from San Juan. Positioned approximately 2,100 feet above sea level, the property enjoys sweeping mountain and valley views, with multiple vantage points offering sunrise, sunset, and 360-degree panoramas. Refreshing mountain breezes and temperatures typically 10–20 degrees cooler than San Juan create an ideal year-round setting. A gated, controlled entrance and fully fenced grounds provide enhanced privacy and security, complemented by remotely accessible security cameras, lighting, and alarm capabilities. Trails throughout the estate allow for exploration by foot, ATV, or 4x4. The estate features two residential structures, including a beautifully remodeled main residence offered fully furnished with brand-new, thoughtfully curated designer pieces for a refined, turnkey living experience. Recent improvements include fresh interior and exterior paint, extensive refinished outdoor decking, and a kitchen equipped with brand-new, high-end appliances. The expansive deck takes full advantage of the surrounding mountain and valley views. The second residence presents additional potential for renovation, while several locations throughout the property has potential building sites for future structures. Historically home to approximately a dozen horses and other livestock, the expansive grounds are well suited for equestrian, agricultural, and recreational use. A-G and B-Q zoning provide further versatility for agricultural, horticultural, eco-tourism, forestry, veterinary, and other permitted uses. The property is well equipped with municipal electricity and water, a 550-foot-deep freshwater well, a 12,000-gallon cistern, two natural creeks, high-speed internet, and a backup generator hookup system. Its abundant sunlight and mountain winds also present potential for future solar and wind energy systems. A rare opportunity to own a truly secluded 100+ acre mountain retreat with exceptional views, infrastructure, and possibilities for generations to come.
