3 Best Sights in North Kona, Big Island

The trails at this sheltered 1,160-acre coastal park near Honokohau Harbor, just north of Kailua-Kona, are popular with walkers and hikers, and the park is a good place to observe Hawaiian archaeological history and intact ruins. These include a heiau (temple), house platforms, ancient fishponds, and numerous petroglyphs along a boardwalk. The park's wetlands provide refuge to waterbirds such as the endemic Hawaiian stilt and coot. Two beaches here are good for swimming, sunbathing, and sea turtle spotting: Aiopio, a few yards north of the harbor, is small and calm, with protected swimming areas (good for kids); Honokohau Beach, also north of the harbor, is a ¾-mile stretch with ruins of ancient fishponds. Of the park's three entrances, the middle one leads to a visitor center with helpful rangers and lots of information. Local docents with backgrounds in geology or other subjects give nature walks. To go directly to the beaches, take the harbor road north of the Gentry retail center, park in the gravel lot, and follow the signs.

On the northernmost stretch of the park's coastline, this lovely beach fronts an absolutely beautiful bay with crystal-clear, deep aquamarine water. It's peaceful in summer, but the park's paved entrance, amenities, and parking lot make the beach very accessible and, as a result, often crowded. Fine white sand sits in stark contrast to old black lava flows, and there's little shade—bring umbrellas. Rocky shores on either side protect the beach from afternoon winds and offer some fabulous snorkeling spots. Gates open daily from 8 to 7. In winter, surf can get rough, and often the sand washes away. Amenities: parking (no fee); showers; toilets. Best for: surfing; swimming.

This coffee producer offers hourly "bean-to-cup" tours, including a tasting and access to the processing plant, which shows dry milling, sizing, coloring, sorting, and roasting. For $10, take the lava tube/nature walk in the cloud forest ecosystem. There's a small retail store where you can purchase coffee and souvenirs. Remember that afternoon rains are common at this elevation, so bring an umbrella and sturdy shoes.
