3 Best Sights in Big Island, Hawaii

A paved, 10-minute loop trail (approximately ½ mile) takes you to the best spots to see the spectacular cascades of Akaka, including the majestic upper Akaka Falls, which drops more than 442 feet. It tumbles far below into a pool drained by Kolekole Stream amid a profusion of fragrant white, yellow, and red torch ginger and other tropical foliage. Another 400-foot falls is on the lower end of the trail. Restroom facilities are available but no drinking water. The park is 4 miles inland, and vehicle parking closes at 6. Visitors are encouraged to reserve parking online in advance at this popular spot.  A series of steps along parts of the trail may prove challenging for some visitors, and they are not wheelchair accessible.

Four separate streams fall into a series of circular pools here, fed by Peepee Falls just above, and the resulting turbulent action—best seen after a good rain—has earned this scenic stretch of the Wailuku River the nickname Boiling Pots. Swimming is not allowed at Boiling Pots or anywhere in the Wailuku River, due to extremely dangerous currents and undertows. The falls are 3 miles northwest of downtown Hilo off Waianuenue Avenue; keep to the right when the road splits and look for the sign. The gate opens at 7 am and closes at 6 pm. You may want to combine a drive to this site with a visit to Rainbow Falls, a bit closer to downtown.  You may be tempted, as you watch others ignore the signs and climb over guardrails, to jump in, but resist. Swimming is prohibited and unsafe, and people have died here.

After a hard rain, these impressive falls thunder into the Wailuku River gorge, often creating magical rainbows in the mist. Rainbow Falls, sometimes known as the "Hilo Town Falls," are located just above downtown Hilo in Wailuku River State Park. Take Waianuenue Avenue west for a mile; when the road forks, stay right and look for the Hawaiian warrior sign. The falls remain open during daylight. If you're visiting the falls, drive up to Boiling Pots, also inside the park but a bit farther up the road. At Boiling Pots, four streams fall into turbulent pools that resemble cauldrons.
