Waikamoi Ridge Trail

Why hike it

This is the Road to Hana’s easiest rainforest immersion: a short, soothing loop through old-growth forest that smells like rain and hums with birds. Don’t expect grand vistas—this one’s about mossy trunks, ferny understory, and the quiet of a living, breathing forest. Benches, lookouts, and picnic tables make it a true pause button on a long drive.

Route, distance & difficulty

The main loop is roughly 1.0 mile total (some guides say up to 1.2 depending on how you connect the short segments) with about 225 feet of gain. It’s an easy walk overall, but the dirt tread can be slick, with roots and a few short, steeper pitches. Going clockwise tends to feel gentler; counterclockwise hits the steeper bits sooner. Expect 30–60 minutes depending on pace and stops.

What you’ll see

You’ll weave through lush, old-growth rainforest on the windward slopes of Haleakalā—think groves of bamboo, kukui (the state tree), spiky hala, and even mango, with ferns and moss everywhere. Lookouts offer filtered peeks through the canopy, but the star is the forest itself. You’re on the edge of the larger Waikamoi Preserve, part of Hawaiʻi’s Nā Ala Hele trail system, so tread lightly and keep an ear out for birds.

Need to know

• No facilities: no restrooms or water. Bring what you need.
• It’s often muddy and slippery, especially after the frequent rains here. Wear real shoes, not flip-flops.
• Mosquitoes love this place—bug spray pays off.
• Parking is a small mauka-side pullout near mile 9–9.5; arrive early. Do not leave valuables in your car—petty theft happens along the highway.
• There are picnic shelters and tables at the trailhead and along the loop; it’s a great snack stop.

Best time to hike

Year-round works. Mornings are quieter and make parking easier; the forest is shaded all day, so heat isn’t a big issue. After rain, the greenery is extra vibrant—but footing is slick. If you’re chasing sweeping views, skip it; if you want a calm, authentic rainforest break on the drive, this is the one.
