Wilderness Landscape & Natural Heritage
Established in 1909, Kauaʻi Forest Reserve encompasses over 60,000 acres of native Hawaiian forest on the island of Kauaʻi, one of the oldest and wettest islands in the Hawaiian archipelago. The reserve covers the mountainous interior of the island, from elevations near sea level up to over 5,000 feet, including parts of the Alaka‘i Plateau and the highlands surrounding Mount Wai‘ale‘ale, one of the wettest spots on Earth. The area is characterized by dense ohia lehua and koa tree forests, coupled with numerous native ferns, rare birds, and endemic plant species, some of which are critically endangered. Kauaʻi Forest Reserve serves as a vital watershed, feeding many of the island’s rivers and waterfalls. It also supports important ecological research and native species restoration efforts. Recreation includes hiking remote trails such as the Alaka‘i Swamp Trail and portions of the Na Pali Coast Trail, providing dramatic views of deep canyons, lush valleys, and waterfalls. Visitors may spot native bird species like the ‘io (Hawaiian hawk) or the endangered ‘apapane honeycreeper. The reserve’s remote terrain means that access can be challenging, requiring permits for some trails and caution for river crossings and variable weather. Despite its relative seclusion, it remains a popular destination for experienced hikers and nature enthusiasts seeking to experience Kauaʻi’s rich natural and cultural heritage.
