The island of Hawaii with its many different ecosystems and low population density is made for hikes and there are enough trails to keep you entertained for months. Our five favorite hikes on the Big Island are a good guide for when you don’t have enough time on our island to ‘see it all’.
Like most visitors you probably only have time for one or two short hikes during your stay on the Big Island. This is why we have put together this list with five short hikes which we consider the “low hanging fruits”. Each hike on this list shows a different highlight of Hawaii and takes between ~1 hour up to half a day:

Kīlauea Iki Trail#
(4 miles round trip, difficulty: medium, Hawaii Volcanoes National Park)
This is the hike we recommend the most if you only have time for one hike during your visit to Hawaii!
Summary: the Kīlauea Iki trail will lead you through a lush ohia forest down into the Kīlauea Iki crater, straight over the crater floor past warm and steaming fissures in the ground. The crater floor was formed almost 60 years ago (in 1959, more about the Kīlauea Iki crater eruption), and the small ohia shrubs are only now starting to grow in the cracks of the solidified lava.
Directions: The Kīlauea Iki trail is located inside the Hawaii Volcanoes National Park at the Kīlauea Iki overlook parking lot.
The hike: Looking towards the crater pick up the trail turning rights following the trail, which slowly descends into the crater through a lush rainforest. Once you reach the crater look down to the ground every now and then. In and between the cinders you can find the little green crystals (olivines) that are also responsible for the green color of the sand at Papakolea beach. On the far side of the crater the trail goes up again. After a steep climb you pass the Thurston Lava Tube (well worth a 30 minute detour). You can find a more elaborate trail guide for this hike at the national park website.
We rate this hike as moderately difficult even though it is relatively short because you have to climb in and out of the crater. This means there are two relatively short stretches during which you have to cover 400 vertical feet up and down. We recommend that you start on this hike early (8 a.m.) to beat the heat and the crowds. Starting early also lets you hear the birds when they are most active and gives you the best photo opportunities.
Tip to avoid crowds: Park at Devastation and embark on a six-mile (9.7 km) round-trip hike into, up, and around Kīlauea Iki from Uēaloha (Byron Ledge). The scenery includes panoramic views of Kīlauea caldera, Mauna Loa (on clear days), and native forest with tall tree ferns.
About the Kīlauea Iki eruption: At November 14, 1959, a spectacular eruption began and flooded the crater with 68 million tons of lava, creating a lava lake several hundred feet deep, and a dramatic fountain that ejected lava 1,900 feet (580 meters) into the sky. The eruption ended five weeks after it started, and the surface of the lava lake solidified. Today, you can hike over that solidified lava lake on what hikers consider to be one of the finest trails in the park.
