Puaa Kaa State Wayside Park is a state park located on the eastern side of the Hawaiian island of Kauai. The park consists primarily of an overlook area with few formal trails, making it popular among hikers and cyclists. It has several pullouts along the 11-mile (18km) Na Pali Coast mountain trail where one can stop for picnics or to take in the view.
The park was established in 1970, but did not open until 1974 because of budget constraints. A new master plan for park development was completed in 2019. Work started that year on developing the main entrance road, parking areas, picnic sites, and other amenities as part of $52 million in improvements announced by Governor David Ige. Plans called for further improvements including expanding camping facilities and installing wireless internet access hubs.
In 2020, work continued on improving the beach at Puu Kuili, which serves as the western terminus of the Na Pali Coast Trail; constructing a “welcome center” with information about local flora and fauna; establishing a campground with hookups for electric vehicles; building two additional parking lots; upgrading the roads to handle heavier traffic; adding water taxi landings and docks; updating outdated restroom facilities; and more. If all goes according to plan, Puaa Kaa will be ready for visitors by late 2022.
