Drive past acres of macadamia nut trees to Hershey-owned Mauna Loa, which offers a self-guided tour of its working factory. Watch the prized mac nut move along the assembly line from cracking and roasting to chocolate dipping and packaging. The gift shop sells the finished product at decent prices, along with mac nut ice cream (single scoop $3.75) on the back patio. Store open daily; factory closed weekends and holidays.
To get here, follow signage about 5 miles south of Hilo; along the 3-mile access road, see acres of macadamia trees.
