5 Best Sights in Big Island, Hawaii

The stunning 4-mile loop hike descends 400 feet into a massive crater via a forested nature trail. When you hike across the crater floor, you're actually walking on a solidified lava lake. Still steaming in places, the crater is dotted with baby ohia trees emerging from the cracks. Venture across the crater floor to the Puu Puai cinder cone that was formed by spatter from a towering lava fountain during the 1959 Kilauea Iki eruption. There are three different trailheads for Kilauea Iki; the main one, which takes two or three hours, begins at the Kilauea Iki Overlook parking lot off Crater Rim Drive. You can also access the crater from Devastation Trail or Puu Puai on the other side. Easy. Bring water, snacks, a hat, sunscreen, and hooded rain gear, as weather can change at a moment's notice.

The Mauna Ulu lava flow presents an incredible variety of geological attractions within a moderate, 2½-mile round-trip hike. The diverse lava landscape was created during the 1969–74 Mauna Ulu flow, which produced enormous "lava falls" the size of Niagara Falls. Visitors can see everything from lava tree molds and fissure vents to cinder cones and portions of the old highway still exposed under the flow. Hawaiian nene geese roam the area, feeding on ripe ohelo berries. Hike to the top of a small hill that survived the flow for incredible views of the distant geological landmarks. On clear days, you can see Mauna Loa, Maunakea, and the Pacific Ocean from atop this hill, known as Puu Huluhulu. Moderate. Purchase the Mauna Ulu trail booklet at the Kilauea Visitor Center for under $3. This excellent resource includes trailside attractions, trail maps, history, and photographs.

A paved pathway takes visitors across a barren lavascape strewn with chunky cinders that descended from towering lava fountains during the 1959 eruption of nearby Kilauea Iki Crater. The easy 1-mile (round-trip) hike ends at the edge of the Kilauea Iki Crater. This must-see view of the crater could yield such memorable sights as white-tailed tropic birds gliding in the breeze or a rainbow stretching above the crater's rim after a sunlit rain shower. Easy.

While mostly rocky topography makes swimming and snorkeling a bit difficult here, this little park is still scenic and relaxing. Take the short trail over to the petroglyph trail; interpretive signs will guide you. There are showers, picnic tables, and restrooms; public parking is limited

People take this short hike, 1.6 miles round-trip, to see faded human footprints, fossilized in hardened volcanic ash. Easy.
