The state Division of Forestry and Wildlife on Saturday reopened the 2.1-mile-long Nualolo Cliff hiking trail, following completion of work by state trail crews to reroute portions of the trail that were washed out and eroded.

Nualolo Cliff Trail is in the Na Pali-Kona Forest Reserve and is managed by the division’s Na Ala Hele Trail and Access Program.

The Nualolo Cliff Trail reroute project bypasses the damaged section by constructing a quarter-mile-long wildland trail with a 2- to 3-foot-wide tread. As a result, Nualolo Cliff Trail now connects with the Nualolo Trail at about the 2.5-mile marker.

Construction of the trail reroute also involved clearing vegetation, trail construction and installation of trail signs. Crews from the Department of Land and Natural Resources got help from the Hawaii Youth Conservation Corps.

The trail had been closed since May 9, 2013, because of hazardous conditions on a 300-foot-long steep cliffside section near the 1.5- and 1.75-mile markers. This stretch was damaged from wear and tear, and with a path only 6 inches wide in places, it was deemed unsafe.

Weather conditions and loose soil also had generated small slides, making repair of the existing trail impractical. The trail skirted a 1,500- to 2,000-foot drop.
