3 Best Sights in Pupukea, North Shore

Made popular in that old Beach Boys song "Surfin' U.S.A.," this is a slice of big-wave (25 to 30 feet) heaven in winter. Summer is the time to swim and snorkel in the calm waters, and the beach is good for families then. The shore break is great for novice bodysurfers. Due to the beach's popularity, its postage-stamp parking lot is often full, but it's also possible to park along the side of the road and walk in. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: snorkeling; surfing; swimming.

Waimea gets lots of press for the giant winter waves in the bay, but the valley itself is a newsmaker and an ecological treasure, with a local nonprofit working to conserve and restore its natural habitat. Follow the Kamananui Stream up the valley through the 1,875 acres of gardens. The botanical collections here have more than 5,000 species of tropical flora, including a superb gathering of native Hawaiian and international plants. It's the best place on the island to see native species, such as the endangered Hawaiian moorhen. You can visit the restored Hale o Lono heiau (shrine) and other ancient archaeological sites as well; evidence suggests that the area was an important spiritual center. Daily activities include botanical walking tours and cultural tours. This is also the venue for the Haleiwa Farmers' Market every Thursday from 2 to 6. At the back of the valley (a ¾-mile walk one-way), Waihi Falls plunges 45 feet into a swimming pond. Bring your board shorts—a swim is the perfect way to end your hike, although the pond can get crowded. Bring mosquito repellent, too; it can get buggy.

What sets Ehukai apart is the view of the famous Banzai Pipeline, where the winter waves curl into magnificent tubes, making it an experienced wave-rider's dream. It's also an inexperienced swimmer's nightmare. Spring and summer waves, on the other hand, are more accommodating to the average person, and there's good snorkeling. Except when the surf contests are happening, there's no reason to stay on the central strip. Travel in either direction from the center, and the conditions remain the same but the population thins out, leaving you with a magnificent stretch of sand all to yourself. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: snorkeling; surfing.
