A shaded loop through an ancient forest island in younger lava.
Overview
Kīpukapuaulu is an easy 1.2-mile loop through a native forest island surrounded by younger lava. It is a shaded nature walk whose payoff is seeing how much plant and animal life fits into this older patch of forest. Allow one to one and a half hours if you stop at the numbered interpretive posts.

Trail guide
Start and finish at the Kīpukapuaulu parking area off Mauna Loa Road. At the fork, take the left branch for the clockwise loop. The dirt path is fairly level, with a few short rises and dips, though some footing is uneven and rocky. The numbered stops are much easier to appreciate if you bring the trail guide. Pit toilets are at the nearby picnic area, not at the trailhead. Dogs, horses, and bicycles are not allowed.
A kīpuka is older land left surrounded by younger lava. The forest here grows on lava at least 8,600 years old, while the surrounding flow is about 600 years old. Layers of volcanic ash built deep, moisture-holding soil; the trail guide describes more native tree species per acre here than in any other forest in the park.
Cattle and feral goats once damaged this forest. Cattle were removed in 1928, and goats and pigs were fenced out in 1968. Civilian Conservation Corps workers built the trail in 1934. Later, volunteers pulled invasive nasturtium by hand, giving dormant koa seeds room to sprout. You can see the recovery in the young koa and in the mix of native ferns and herbs along the path.
Watch the māmaki shrubs for Kamehameha butterflies and the forest floor for Kalij pheasants, introduced to Hawaiʻi in 1962. Birdsong is easier to count on than a close sighting; the forest is worth the walk even when the birds stay hidden.
At stop six, a skylight opens into a lava tube beneath the forest. The tube is at least 8,600 years old, and the first cave-adapted animal species known in Hawaiʻi was discovered there in 1971. The small-eyed, big-eyed hunting spider is one of the unusual animals associated with these dark tubes. Stay on the path; entering the tube is discouraged because its geology and wildlife are fragile.
