Puaʻa Kaʻa State Wayside Park

Tucked along the legendary Hana Highway on Maui’s lush north shore, Puaʻa Kaʻa State Wayside Park is one of the most accessible waterfall stops on the Road to Hana. This roadside gem near Haiku in Maui County offers travelers a chance to stretch their legs, cool off beneath a cascading waterfall, and soak in the dense tropical beauty that defines this stretch of coastline.

The park’s main draw is its tiered waterfall and natural pool, reached by a short trail from the parking area. The pool is deep enough for swimming on most days, making it a refreshing stop during the winding drive to or from Hana. A second, lesser-known upper falls rewards those willing to scramble a bit further upstream. The surrounding rainforest drips with ferns, bamboo, and wild ginger, creating a scene that feels genuinely primordial.

Facilities are modest — expect restrooms and a few picnic tables, but no camping or overnight accommodations. Pack a lunch and enjoy it alongside the sound of falling water. The park tends to get crowded midday when tour vans arrive, so early morning or late afternoon visits offer a quieter experience.

The best time to visit is during Maui’s drier months from April through October, though the waterfalls flow strongest after winter rains. Be prepared for slippery rocks near the water and bring reef-safe sunscreen. With a 4.7-star rating across 630 reviews, Puaʻa Kaʻa consistently ranks among the most beloved stops on the Hana Highway — and it earns every bit of that reputation.
