Step into this coral-and-rock house on Lahaina’s Front Street and travel back in time. Built in 1835, it belonged to Rev. Dwight Baldwin, a missionary, naturalist, and self-trained physician who saved many Native Hawaiians from devastating influenza and smallpox epidemics. Baldwin’s rudimentary medical tools (on display here) bear witness to the steep odds he faced. He was rewarded with 2,600 acres in Kapalua, where he grew pineapple—then an experimental crop. His children later became some of Hawaii’s most powerful landholders and business owners. Tour the Baldwin family home and pick up a walking-tour map to Lahaina’s most historic sites on your way out. On Friday night, docents dressed in period attire offer candlelit tours and serve free refreshments on the lanai.
