Oahu isn't the only island where you can take a guided tour - Circle Island tours are available on Maui, the Big Island, Molokai and Kauai. Travel interisland via jet, Volcano tours leave from Hilo for the most part, but a few start in Kona and make the long drive to the volcano, where many visitors actually get to see the red-hot lava. Fly-drive packages are also available - rent a car, and take a helicopter tour, play a round of golf, or scuba amongst the honu ( green sea turtles ) and spinner dolphins.
