This infrequently maintained, unpaved, 4wd public access route passes
through Kapapala Ranch for 5.7 miles before entering the Kapapala
Forest Reserve and continuing another 2.3 miles to the Ainapo
Trailhead. Except for non-native grasses, the forest reserve is an
excellent example of native mixed mesic koa/ohia forest, offering many
opportunities to observe native forest birds such as Apapane, I`iwi,
Amakihi and Elepaio.
Ainapo Road begins at the cattle guard located on the mauka side of
Highway 11 in Ka`u, at approximately the 40.5 mile mark. Open during
daylight hours only. Parking at either end on unvegetated sides of road
and at trailhead.
Forest Reserve and Ranch are open to public hunting year round. Bright
clothing is recommended.
