Visitors can explore a historic Maui structure built in 1874 for King David Kalakaua and Queen Kapi'olani, which later served as a retreat for the monarch during his reign. The site includes a tasting room featuring an 18‑foot bar carved from a single mango tree and shelves stocked with locally produced goods, and offers packaging options for wine transport. The surrounding grounds, shaded by century‑old trees, preserve the remains of the former Rose Ranch sugar plantation and now function as the headquarters of Ulupalakua Ranch, the base for the Hawaiian cowboy tradition.
