4. Hawaii, The Big Island
The largest of all Hawaii islands, the Big Island has everything from flourishing forests to active volcanoes to boating to snorkeling. Then, there is hiking via the popular Hawaiian Volcanoes National Park as well as the Hakalau Forest. If you are looking for a less intense adventure, hike inside the Akaka Falls State Park that sweetly culminates at the gushing Kahuna Falls and Akaka Falls.
