2 Best Sights in Hawi and Kapaau, Big Island

Snorkelers and divers often make exciting discoveries in the clear waters of this park, now a swimming hole and an underwater museum of sorts. Amazingly, it's also home to a dormant, submerged shield volcano of the same name with a summit of 9,500 feet, showcasing just how deep it gets right offshore. Long ago, when sugar was the economic staple of Kohala, this harbor was busy with boats waiting to make overseas shipments. Now remnants of shipping machinery, train wheels and parts, and what looks like an old boat are easily visible in the clear water. There's no actual beach here, but a ladder off the old dock makes getting in the water easy. Venture out only on tranquil days, though, when the water is calm; conditions can get windy and the ocean choppy.

A popular place with locals, Mahukona is busy on weekends. A camping area on the south side of the park has picnic tables and an old covered pavilion. A trail also leads to nearby Lapakahi State Park, about a ½-mile hike. Amenities: showers; toilets. Best for: snorkeling; swimming.

At the tip of North Kohala, this is one of the Big Island's most scenic beaches. Rain and erosion over millennia have created a stunning, deep-cut windward valley with a windswept gray-sand beach that is piled with large, round boulders and driftwood and backed by ironwood trees and sheer green cliffs. The trail is steep and rocky; it can also be muddy and slippery, so use caution. A Pololu Trail Steward program stations local “stewards” at the trailhead to share historical and cultural perspectives of the valley. Please visit with respect for the land and for all area residents. This is not a safe swimming beach even though locals swim, body board, and surf here. Rip currents and usually rough surf pose a real hazard. Because this is an isolated area far from emergency help, extreme caution is advised. Amenities: none. Best for: solitude.
