Wai'anapanapa State Park, HI: Shoreline Trail

This coastside trail in Wai'anapanapa State Park packs so many photo-worthy views into its two miles that it can easily occupy half a day. Bonus: Take a post-hike dip in a freshwater cave.

Three miles from Hana, on the west side of Maui, Wai’anapanapa State Park is a coastal playground; a rugged volcanic shoreline, blowholes shooting fountains of seawater into the sky, arches of lava rock stretching into the waves, caves and lava tubes for exploring, or just the novelty of kicking back on a pristine Hawaiian black sand beach.
For the coast trail, start along a paved walkway offering views over the Pa’iloa black sand beach. A short walkway branches off the trail descending to the beach and the opening of a lava tube. Pass an old cemetery and the camping area, and where the pavement ends head left off trail to the rocky outcropping of lava for a closeup view – but not too close! – of a large blowhole and a long lava arch. You may be tempted to just park it here and watch the ocean put on its show, but there’s more to see.
Back on trail, follow the path as it contours along the coast, keeping left at all junctions, past dense groves of hala (not pineapple) trees, giving more views of the ragged volcanic coastline, with more arches, blowholes, and collapsed lava tubes. Cross a narrow rocky bridge over a collapsed tube and notice the surf churning below. Descend a large rock step and continue along around the remains of an ancient heiau (temple) and through an overgrown grassy area to a spot with numerous rock wall remains from an old village with more hala and nice views. The trail continues all the way to Hana, but gets sketchy from here on – and all the best views are behind you – so this spot makes a good turnaround point.
For the freshwater caves loop, head north from the parking area to a large sign telling the legend of Princess Popoalaea and the freshwater caves. Less than half way along the quarter-mile loop brings you to the first – and only swimmable – cave. Bring an underwater light to explore the two chambers beyond the opening. The second pool on the loop is pretty murky and not inviting. Finish up where you began, and spend some time on the small, yet utterly gorgeous black sand beach.
Warning: Do not approach blowholes, and use extreme caution on the lava benches nearest the ocean, as many of these areas are unstable. Be aware of high surf conditions.
