History buffs adore this plantation museum, but kids may grow restless. Grove Farm once ranked among the most productive sugar companies on Kauaʻi. George Wilcox, the Hilo-born son of Protestant missionaries, acquired the farm in 1864. The main house feels suspended in time, with rocking chairs sitting still on a covered porch and untouched books lining the library's shelves.
Call a week or more in advance to join a small-group tour, which includes cookies and mint tea served on the lanai.
