Out of all the parks in Hawaii, Koke'e State Park offers the most variety by far. There are over 15 trails intermingling throughout the lush Kalalau valley which range from .5 to 4 miles in length. Koke'e State Park offers unpralelled views along with numerous chances to see local plants and wildlife face to face. The park receives over 70 inches of rain per year.
Located just North of the Waimea Canyon State Park, Koke'e State Park also houses a museum, resistant, and a gift shop. There are also cabins available to rent. Koke'e State Park is accessible from the 15 mile marker on Highway 50. View the park's site here.
