Popular even with novice hikers, this boulder-strewn trail offers a cool retreat amid Norfolk pines and endemic plants, with ridgetop views of Honolulu and Waikiki. Rolling up and down a series of small saddles and knobs before reaching a grassy clearing, the 4.8-mile round-trip trail covers a variety of terrain in a short time, making an enjoyable afternoon’s walk.

Look for the Na Ala Hele trailhead sign beyond the picnic tables inside Waʻahila Ridge State Recreation Area, at the back of the St Louis Heights subdivision, east of Manoa Valley.

If you are traveling by car, turn left off Waiʻalae Ave onto St Louis Dr at the stoplight. Heading uphill, veer left onto Bertram St, turn left onto Peter St, then turn left again onto Ruth Pl, which runs west into the park. From Waikiki, bus 14 St Louis Heights stops at the intersection of Peter and Ruth Sts, which is about a half-mile walk from the trailhead.
