One of Maui’s best hikes, this trail climbs 800 feet through the lush Kipahulu area of Haleakala National Park. Half a mile from the visitor center, an overlook provides sweeping views of the gorge and the almost-200-foot-long “horsetail” of Makahiku Falls. Continue on past a sprawling banyan, stopping to marvel at the sunlight trickling through the dense bamboo forest. Here, you’ll also find the even more dramatic cascade of Waimoku Falls, which plunges 400 feet down a sheer-walled lava amphitheater. If you’re wary of tackling the four-mile round-trip hike by yourself, know that park rangers offer guided tours every Sunday at 10 a.m. Reservations are available at 9 a.m. a week ahead of time.
