Rafting in Maui

The high-speed, inflatable rafts you find on Maui are nothing like the raft that Huck Finn used to drift down the Mississippi. While passengers grip straps, these rafts fly, skimming and bouncing across the sea. Because they're so maneuverable, they go where the big boats can't—secret coves, sea caves, and remote beaches. Two-hour trips run around $50, half-day trips upward of $100. Although safe, these trips are not for the faint of heart. If you have back or neck problems or are pregnant, you should reconsider this activity.

Tours

Blue Water Rafting. One of the few ways to get to the stunning Kanaio Coast (the roadless southern coastline beyond Ahihi-Kinau), this rafting tour begins trips conveniently at the Kihei boat ramp. Dolphins, turtles, and other marine life are the highlight of this adventure, along with sea caves, lava arches, and views of Haleakala. Two-hour trips start at $49 plus tax; longer trips cost $90 to $115 and include a deli lunch. 2777 S. Kihei Rd., Kihei, 96753. 808/879-7238. www.bluewaterrafting.com.

Ocean Riders. This West Maui tour crosses the AuAu Channel to Lanai's Shipwreck Beach, then circles the island for 70 mi of remote coast. For snorkeling, the "back side" of Lanai is one of Hawaii's unsung marvels. Tours—$129 plus tax per person—depart from Mala Wharf, at the northern end of Front Street and include snorkel gear, a fruit breakfast, and a deli lunch.
