Things to Do
Hawaii state parks protect some of the most stunning landscapes on Earth — from active volcanic calderas and tropical rainforests to pristine coral reef bays and dramatic sea cliffs. Activities include hiking through lush valleys and along volcanic crater rims, snorkeling in crystal-clear protected bays, swimming at world-class tropical beaches, surfing legendary breaks, camping in beachfront and forest settings, kayaking along Na Pali-style coastlines, stargazing at high-altitude sites, and exploring ancient Hawaiian heiau (temples) and petroglyph fields.
Best Time to Visit
Hawaii parks are a year-round destination with consistently warm temperatures (75-85°F). The dry season (April–October) offers the best beach and hiking conditions. The wet season (November–March) brings bigger surf on north shores, whale watching (humpbacks arrive December–April), and lusher waterfalls, though trail conditions can be muddy. Windward (east) sides of each island receive significantly more rain than leeward (west). High altitude parks like Haleakalā can be cold (below 40°F) — bring layers regardless of season.
Visitor Tips
Many Hawaii state parks are free to enter. About a dozen popular parks charge non-residents $5 per person plus $10 parking, and two Oʻahu waysides charge $7 parking; Hawaii residents enter free with ID. Diamond Head, Hāʻena and Waiʻānapanapa require advance reservations for non-residents. Camping permits must be obtained through the DLNR website in advance. Respect Hawaiian cultural sites — never remove rocks, sand, or artifacts. Many trails close after heavy rain for safety. Reef-safe sunscreen is required by law in Hawaii. Always check current conditions before hiking, as flash floods are a real danger in valley trails.
