Hikers won't be disappointed with the diversity and challenges of hiking this big island. The island is networked with trails from seashore to summit, and plenty of places in between. Trails vary from easy, well-marked hiking paths to steep, rugged mountain trails, from treks through lava fields to backcountry routes on private land available only with guides.

If you go with a hiking company, you're likely to get more than a workout. Some companies design packages that combine hiking with nature and cultural experiences. One of the best waterfall hikes follows a path along mountain streams, over footbridges and under seven waterfalls to a taro patch where you can unlace your boots and wiggle your toes in a muddy ancient Hawaiian lo'i, restored and replanted with taro. Swim in a mountain stream gurgling with waterfalls and discover how early Hawaiians harnessed water to feed their crops.

The trail is less than a half mile from the rim of Pololu Valley, a spectacular wilderness area at the end of the paved road past Hawi and Kapa'au in North Kohala.

Volcanoes National Park is a spectacular place to hike. Hawaii Forest & Trail will take you there, but it also offers tours of a lesser known volcano called Hualalai. Located a short drive from Kailua-Kona, Hualalai offers a quick study in volcanism without the innate hazards of an active volcano. Tour guides will deliver a lesson in volcanism and the historic eruptions that changed the landscape of the Kona Coast below.

Public access trails on the island are administered by Hawaii Volcanoes National Park (985-6000), the Hawaii Division of Forestry and Wildlife (974-4221), and the Hawaii Division of State Parks (974-6200). Contact these agencies for permits, reservations, current information concerning hiking, etc. These agencies also provide free, literature on the lands under their jurisdiction.
