North of Waimea on Kauai, the Kalepa Ridge Trail is a popular Kauai mountain biking trail. It is an unofficial and unmaintained hunters path that follows the ridge line between the Honopu Valley and Kalalau Valley.
The Kalepa Ridge Trail is for experienced, fearless, hardcore mountain bikers. There are sections of the trail that run cliffside along 1,000 foot drops. The trail should only be ridden when it is dry and rain is not forecasted; there are several very steep sections that become impassible when wet.
The trailhead starts at the Kalalau Lookout at the far northern end of Koke’e State Park.
Overall, Kalepa Ridge Trail is the 20th most popular mountain bike trail of all 22 mountain biking rides in Hawaii.
