Hawaii State Forest Reserves protect diverse native ecosystems and volcanic landscapes across the Hawaiian Islands, offering extensive opportunities for hiking, birdwatching, and nature study within its lush forests and volcanic terrains.
The Hawaii State Forest Reserves encompass a network of protected forestlands across several Hawaiian Islands, primarily located on the islands of Hawaii (the Big Island), Maui, Kauai, Oahu, and Molokai. These reserves were established to conserve native Hawaiian forests with their unique plant and animal species, protect watershed areas, and preserve natural and cultural resources. The landscapes within the reserves range from dense native rainforests dominated by koa and ʻōhiʻa lehua trees to alpine shrublands and volcanic slopes. Bird species such as the nēnē (Hawaii’s state bird) and endangered honeycreepers inhabit these forests, offering excellent wildlife viewing opportunities. Historically, many of the reserves have been critical to Hawaiian culture as sources of medicinal plants, timber, and spiritual significance. Visitors today come for hiking on well-maintained trails, camping, and exploring remote wilderness areas. Notable landmarks in the forest reserves include the extensive koa forests of the Mauna Kea Forest Reserve, the native bird sanctuary in the Hakalau Forest Reserve, and the scenic overlook areas with views of volcanic landscapes and deep valleys. The reserves also play a significant role in watershed protection, ensuring freshwater availability to local communities. Despite their natural beauty and ecological importance, many reserves require visitors to practice leave-no-trace principles and adhere to access regulations to protect fragile ecosystems. The reserves provide a serene outdoor experience contrasting with the island’s coastal tourist areas, attracting those seeking wilderness and nature immersion.
