Hiking on the Big Island
Concierge.com's insider take:
Well-marked and challenging trails crisscross Volcanoes National Park (you'll get a map upon entering), including the popular hikes down and across Kilauea Iki Trail, to Napau Trail, along Byron Ledge and the daylong Crater Rim Trail (808-985-6000; www.nps.gov/havo). Lightweights and families can try the 15-minute trek along the Malama Trail, just north of the Mauna Lani resort, to see Hawaiian petroglyphs. For the really hardy, the steep walk down and even more exhausting hike back up the Waipio Valley is worthwhileit's a sacred spot to Hawaiians.
