Waiʻānapanapa Coastal Trail (Ke Ala Loa O Maui / Piʻilani Trail)

What to expect

This historic coastal path traces Waiʻānapanapa State Park’s jagged lava shoreline, starting by the famous Black Sand Beach (Pailoa). Expect nonstop ocean vistas, wave-smashed cliffs, blowholes, sea arches, and tide pools, with almost no shade. Underfoot, it’s sharp, uneven lava—gorgeous but unforgiving—so sturdy closed-toe shoes aren’t optional.

How far to go

Most visitors sample the northbound segment from Black Sand Beach to ʻOhala Heiau, about 0.75 mile one way (roughly 1.5 miles round trip). Plan around 2 hours round trip if you like to stop for photos and birdwatching; the scenery begs for lingering. The trail continues beyond the park around Pukaulua Point and toward Hāna Airport for those wanting more, but the in-park out-and-back delivers the classic experience.

Highlights along the way

Start with the black sand itself, then wander the coastline for lava tubes, small sea caves, and a shoreline blowhole (there’s a short paved approach for an easy viewpoint). The route also passes cultural sites—ʻOhala Heiau among them—so give these areas respect and space. Keep an eye out for seabirds and, in season, humpback whales offshore.

Trail feel and conditions

It’s a moderate trek: little elevation but constant uneven, sharp lava and exposure. After rain, the rock can be slick, and this coast is famously breezy with passing showers. This is less a stroll and more a careful wander—take your time and watch your footing.

Logistics and access

Park at the Waiʻānapanapa State Park Black Sand Beach lot. Non-residents must have advance reservations to enter the park; without one you’ll be turned around even if it looks quiet. Restrooms are by the trailhead area. If you’re short on time, at least do the paved blowhole/viewpoint section for a quick taste.

Best time to hike

Year-round works, but early morning or late afternoon has softer light, fewer crowds, and (often) slightly cooler temps. Midday can be hot and harsh with minimal shade. Expect wind and be ready for brief showers any time.

Tips

• Wear real shoes—lava will chew up sandals and toes.
• Pack water, sun protection, and respect any closures around caves or cliff areas.
• Stay well back from blowholes and cliff edges—surge can be unpredictable.
