Manuka State Wayside
Located near the subdivision of Ocean View, this lowland forest reserve spreads across several relatively recent lava flows, offering a semi-rugged trail that follows a 2-mile loop past a pit crater and winding around interesting trees such as hau and kukui (candlenut). You can wander through the well-maintained arboretum, snap photos of the eerie forest, and let the kids scramble around trees so large they can't get their arms around them. The pathways can get muddy and rough, so bring appropriate shoes if you plan to hike. Large populations of the Hawaiian hoary bat inhabit the area, which, in totality, encompasses 25,000 acres of forest reserve. Restrooms and picnic areas are available.
