If you love little quirks of history, make sure to pop into this unassuming museum. It's essentially a house (specifically an old station agent's house) of cool stuff, brimming with fascinating artifacts and photographs of the plantation railroad era. Don't miss the video of the long-gone coastal train, which showcases the amazing bridges that once curved along (and across) Hamakua gulches, until demolished by tsunami. Located between mile markers 25 and 26.
