2 Best Sights in Kawaihae, Big Island

Quite simply, this is one of the most historic and commanding sites in all of Hawaii: here, in 1810, on top of Puukohola (Hill of the Whale), Kamehameha the Great built the war heiau, or temple, that would serve to unify the Hawaiian Islands, ending 500 years of warring chiefdoms. The oceanfront, fortresslike site is foreboding and impressive. A paved ½-mile looped trail runs from the visitor center to the main temple sites. An even older temple, dedicated to the shark gods, lies submerged just offshore, where sharks can be spotted swimming, usually first thing in the morning. A museum displays ancient Hawaiian weapons, including clubs, spears, a replica of a bronze cannon that warriors dragged into battle on a Hawaiian sled, and three original paintings by artist Herb Kane. This underrated park is often very uncrowded. Rangers are available to answer questions, or you can take a free audio tour on your smartphone. Plan about an hour to see everything.

Popular with local families because of its reef-protected waters, this white-sand beach is probably the safest beach in West Hawaii for young children. It's also generally safe for swimming year-round, which makes it a reliable spot for a lazy day at the beach. There is a little shade, plus a volleyball court and pavilion, and the soft sand is perfect for sand castles. It tends to get crowded with families and campers on weekends, but the beach is mostly clean. You won't see a lot of fish if you're snorkeling here, but in winter you can often catch sight of a breaching whale or two. The beach park lies just below Puukohola Heiau National Historic Site. Amenities: lifeguards (weekends and holidays only); parking (no fee); showers; toilets. Best for: sunset; swimming.
